1.2 Description
The TMS320C64x+™ DSPs (including the TMS320DM6433 device) are the highest-performance
fixed-point DSP generation in the TMS320C6000™ DSP platform. The DM6433 device is based on the
third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture
developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media
applications. The C64x+™ devices are upward code-compatible from previous devices that are part of the
C6000™ DSP platform. The C64x™ DSPs support added functionality and have an expanded instruction
set from previous devices.
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and
C64x+ CPU, respectively.
With performance of up to 5600 million instructions per second (MIPS) at a clock rate of 700 MHz, the
C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possesses
the operational flexibility of high-speed controllers and the numerical capability of array processors. The
C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly
independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The
eight functional units include instructions to accelerate the performance in video and imaging applications.
The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2800 million
MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 5600 MMACS. For more details
on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide
(literature number SPRU732).
The DM6433 also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000 DSP platform devices. The DM6433 core uses a two-level
cache-based architecture. The Level 1 program memory/cache (L1P) consists of a 256K-bit memory
space that can be configured as mapped memory or direct mapped cache, and the Level 1 data (L1D)
consists of a 640K-bit memory space —384K-bit of which is mapped memory and 256K-bit of which can
be configured as mapped memory or 2-way set-associative cache. The Level 2 memory/cache (L2)
consists of a 1M-bit memory space that is shared between program and data space. L2 memory can be
configured as mapped memory, cache, or combinations of the two.

The peripheral set includes: 1 configurable video port; a 10/100 Mb/s Ethernet MAC (EMAC) with a
management data input/output (MDIO) module; a 4-bit transmit, 4-bit receive VLYNQ interface; an
inter-integrated circuit (I2C) Bus interface; a multichannel buffered serial port (McBSP0); a multichannel
audio serial port (McASP0) with 4 serializers; 2 64-bit general-purpose timers each configurable as
2 independent 32-bit timers; 1 64-bit watchdog timer; a user-configurable 16-bit host-port interface (HPI);
up to 111-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation
modes, multiplexed with other peripherals; a UART with hardware handshaking support; 3 pulse width
modulator (PWM) peripherals; 1 peripheral component interconnect (PCI) [33 MHz]; and 2 glueless
external memory interfaces: an asynchronous external memory interface (EMIFA) for slower
memories/peripherals, and a higher speed synchronous memory interface for DDR2.
The DM6433 device includes a Video Processing Subsystem (VPSS) with a Video Processing Back-End
(VPBE) output.
The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and a
Video Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separate
OSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute window
allowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz,
providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENC
also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of
8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.
The Resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in increments
of 256/N, where N is between 64 and 1024.
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6433 and
the network. The DM6433 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps)
and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS)
support.
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The I2C and VLYNQ ports allow DM6433 to easily control peripheral devices and/or communicate with
host processors.
The rich peripheral set provides the ability to control external peripheral devices and communicate with
external processors. For details on each of the peripherals, see the related sections later in this document
and the associated peripheral reference guides.
The DM6433 has a complete set of development tools. These include C compilers, a DSP assembly
optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into
source code execution.

2.2 CPU (DSP Core) Description
The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and two
data paths as shown in Figure 2-1. The two general-purpose register files (A and B) each contain
32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be
data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit
data, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are
stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or
32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one
instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units
perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from
memory to the register file and store results from the register file into memory.
The C64x+ CPU extends the performance of the C64x core through enhancements and new features.
Each C64x+ .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x
32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with
add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four
16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for
Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and
modems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs
and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding
capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The
32 x 32 bit multiply instructions provide the extended precision necessary for audio and other
high-precision algorithms on a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a
pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data
performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2
comparisons were only available on the .L units. On the C64x+ core they are also available on the .S unit
which increases the performance of algorithms that do searching and sorting. Finally, to increase data
packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit
and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack
instructions return parallel results to output precision including saturation support.
Other new features include:
•
SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size
associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.
•
Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+
compiler can restrict the code to use certain registers in the register file. This compression is
performed by the code generation tools.
•
Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.

•
Exceptions Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to
detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and
from system events (such as a watchdog time expiration).
•
•
Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a
basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with
read, write, and execute permissions.
Time-Stamp Counter - Primarily targeted for Real-Time Operating System (RTOS) robustness, a
free-running time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

2.3 C64x+ CPU
The C64x+ core uses a two-level cache-based architecture. The Level 1 Program memory/cache (L1P)
consists of 32 KB memory space that can be configured as mapped memory or direct mapped cache. The
Level 1 Data memory/cache (L1D) consists of 80 KB—48 KB of which is mapped memory and 32 KB of
which can be configured as mapped memory or 2-way set associated cache. The Level 2 memory/cache
(L2) consists of a 128 KB memory space that is shared between program and data space. L2 memory can
be configured as mapped memory, cache, or a combination of both.
Table 2-2 shows a memory map of the C64x+ CPU cache registers for the device.

(1) For all bootmodes that default to DSPBOOTADDR = 0x0010 0000 (i.e., all boot modes except the EMIFA ROM Direct Boot,
BOOTMODE[3:0] = 0100, FASTBOOT = 0), the bootloader code disables all C64x+ cache (L2, L1P, and L1D) so that upon exit from the
bootloader code, all C64x+ memories are configured as all RAM (L2CFG.L2MODE = 0h, L1PCFG.L1PMODE = 0h, and
L1DCFG.L1DMODE = 0h). If cache use is required, the application code must explicitly enable the cache. For more information on boot
modes, see Section 3.4.1, Boot Modes. For more information on the bootloader, see the Using the TMS320DM643x Bootloader
Application Report (literature number SPRAAG0). For the EMIFA ROM Direct Boot (BOOTMODE[3:0] = 0100, FASTBOOT = 0), the
bootloader is not executed—that is, L2 RAM/Cache defaults to all RAM (L2CFG.L2MODE = 0h); L1P RAM/Cache defaults to all cache
(L1PCFG.L1PMODE = 7h); and L1D RAM/Cache defaults to all cache (L1DCFG.L1DMODE = 7h).
(2) The EMIFA CS0 and CS1 are not functionally supported on the DM6433 device, and therefore, are not pinned out.

2.5 Pin Assignments
Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in
the smallest possible package. Pin multiplexing is controlled using a combination of hardware
configuration at device reset and software programmable register settings. For more information on pin
muxing, see TBD, Multiplexed Pin Configurations of this document.
2.5.1 Pin Map (Bottom View)
Figure 2-2 through Figure 2-5 show the bottom view of the ZWT package pin assignments in four
quadrants (A, B, C, and D). Figure 2-6 through Figure 2-9 show the bottom view of the ZDU package pin
assignments in four quadrants (A, B, C, and D).

2.6 Terminal Functions
The terminal functions tables (Table 2-5 through Table 2-31) identify the external signal names, the
associated pin (ball) numbers along with the mechanical package designator, the pin type, whether the pin
has any internal pullup or pulldown resistors, and a functional pin description. For more detailed
information on device configuration, peripheral selection, multiplexed/shared pin, and debugging
considerations, see the Device Configurations section of this data manual.
All device boot and configuration pins (except PCIEN) are multiplexed configuration pins— meaning they
are multiplexed with functional pins. These pins function as device boot and configuration pins only during
device reset. The input states of these pins are sampled and latched into the BOOTCFG register when
device reset is deasserted (see Note below). After device reset is deasserted, the values on these
multiplexed pins no longer have to hold the configuration.
The PCIEN pin is a standalone configuration pin. Its value is latched into the BOOTCFG register when
device reset is deasserted (see Note below). Unlike the multiplexed device boot and configuration pins,
the value on the PCIEN pin even after device reset is deasserted must hold the configuration.
For proper device operation, external pullup/pulldown resistors may be required on these device boot and
configuration pins. Section 3.9.1, Pullup/Pulldown Resistors discusses situations where external
pullup/pulldown resistors are required.
Note: Internal to the chip, the two device reset pins RESET and POR are logically AND’d together for the
purpose of latching device boot and configuration pins. The values on all device boot and configuration
pins are latched into the BOOTCFG register when the logical AND of RESET and POR transitions from
low-to-high.

2.8 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX,
TMP, or TMS (e.g., TMS320DM6433ZWTQ6). Texas Instruments recommends two of three possible
prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of
product development from engineering prototypes (TMX/TMDX) through fully qualified production
devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX
TMP
TMS
Experimental device that is not necessarily representative of the final device's electrical
specifications.
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
Fully-qualified production device.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully qualified development-support product.
TMX and TMP devices and TMDX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.

Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate still is undefined. Only qualified production devices are
to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, ZWT), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, "6" indicates [600-MHz]).

3.2 Power Considerations
The DM6433 provides several means of managing power consumption.
As described in the Section 6.3.4, DM6433 Power and Clock Domains, the DM6433 has one single power
domain—the “Always On” power domain. Within this power domain, the DM6433 utilizes local clock gating
via the Power and Sleep Controller (PSC) to achieve power savings. For more details on the PSC, see
Section 6.3.5, Power and Sleep Controller (PSC) and the TMS320DM643x DMP DSP Subsystem
Reference Guide (literature number SPRU978).
Some of the DM6433 peripherals support additional power saving features. For more details on power
saving features supported, see the peripheral-specific reference guides [listed/linked in the
TMS320DM643x DMP Peripherals Overview Reference Guide (literature number SPRU983).
Most DM6433 3.3-V I/Os can be powered-down to reduce power consumption. The VDD3P3V_PWDN
register in the System Module (see Figure 3-1) is used to selectively power down unused 3.3-V I/O pins.
For independent control, the 3.3-V I/Os are separated into functional groups—most of which are named
according to the pin multiplexing groups (see Table 3-2). For these I/O groups, only the I/O buffers needed
for Host/EMIFA Boot or Power-Up Operations are powered up by default (CLKOUT Block, EMIFA/VPSS
Block, Host Block, PCI Data Block, and GPIO Block).
Note: To save power, all other I/O buffers are powered down by default. Before using these pins, the user
must program the VDD3P3V_PWDN register to power up the corresponding I/O buffers.
For a list of multiplexed pins on the device and the pin mux group each pin belongs to, see
Section 3.7.3.1, Multiplexed Pins on DM6433.
Note: The VDD3P3V_PWDN register only controls the power to the I/O buffers. The Power and Sleep
Controller (PSC) determines the clock/power state of the peripheral.

3.3 Clock Considerations
Global device and local peripheral clocks are controlled by the PLL Controllers (PLLC1 and PLLC2) and
the Power and Sleep Controller (PSC). In addition, the System Module VPSS_CLKCTL register configures
the clock source to the Video Processing Subsystem (VPSS).
3.3.1 Clock Configurations after Device Reset
After device reset, the user is responsible for programming the PLL Controllers (PLLC1 and PLLC2) and
the Power and Sleep Controller (PSC) to bring the device up to the desired clock frequency and the
desired peripheral clock state (clock gating or not).
For additional power savings, some of the DM6433 peripherals support clock gating within the peripheral
boundary. For more details on clock gating and power saving features supported by a specific peripheral,
see the peripheral-specific reference guides [listed/linked in the TMS320DM643x DMP Peripherals
Overview Reference Guide (literature number SPRU983)].
3.3.1.1 Device Clock Frequency
The DM6433 defaults to PLL bypass mode. To bring the device up to the desired clock frequency, the
user should program PLLC1 and PLLC2 after device reset.
DM6433 supports a FASTBOOT option, where upon exit from device reset the internal bootloader code
automatically programs the PLLC1 into PLL mode with a specific PLL multiplier and divider to speed up
device boot. While the FASTBOOT option is beneficial for faster boot, the PLL multiplier and divider
selected for boot may not be the exact frequency desired for the run-time application. It is the user's
responsibility to reconfigure PLLC1 after fastboot to bring the device into the desired clock frequency.
Section 3.4.1, Boot Modes discusses the different fast boot modes in more detail.
The user must adhere to the various clock requirements when programming the PLLC1 and PLLC2:
•
Fixed frequency ratio requirements between CLKDIV1, CLKDIV3, and CLKDIV6 clock domains. For
more details on the frequency ratio requirements, see Section 6.3.4, DM6433 Power and Clock
Domains.
•
PLL multiplier and frequency ranges. For more details on PLL multiplier and frequency ranges, see
Section 6.7.1, PLL1 and PLL2.

3.3.1.2 Module Clock State
The clock and reset state for each of the modules is controlled by the Power and Sleep Controller (PSC).
Table 3-3 shows the default state of each module after a device-level global reset. The DM6433 device
has four different module states—Enable, Disable, SyncReset, or SwRstDisable. For more information on
the definitions of the module states, the PSC, and PSC programming, see Section 6.3.5, Power and Sleep
Controller (PSC) and the TMS320DM643x DMP DSP Subsystem Reference Guide (literature number

3.4 Boot Sequence
The boot sequence is a process by which the device's memory is loaded with program and data sections,
and by which some of the device's internal registers are programmed with predetermined values. The boot
sequence is started automatically after each device-level global reset. For more details on device-level
global resets, see Section 6.5, Reset.
There are several methods by which the memory and register initialization can take place. Each of these
methods is referred to as a boot mode. The boot mode to be used is selected at reset. For more
information on the bootmode selections, see Section 3.4.1, Boot Modes.
The device is booted through multiple means—primary bootloaders within internal ROM or EMIFA, and
secondary user bootloaders from peripherals or external memories. Boot modes, pin configurations, and
register configurations required for booting the device, are described in the following subsections.
3.4.1 Boot Modes
The DM6433 boot modes are determined by these device boot and configuration pins. For information on
how these pins are sampled at device reset, see Section 6.5.1.2, Latching Boot and Configuration Pins.

BOOTMODE[3:0]
PCIEN
FASTBOOT
AEM[2:0]
PLLMS[2:0]
Note: The PLLMS[2:0] configuration pins are actually multiplexed with the AEAW[2:0] configuration pins.
For more details on the multiplexed AEAW[2:0]/PLLMS[2:0] configuration pins and control, see
Section 3.5.1.2, EMIFA Address Width Selects (AEAW[2:0]) and FASTBOOT PLL Multiplier Selects
(PLLMS[2:0]).
BOOTMODE[3:0] and PCIEN determine the type of boot (e.g., I2C Boot, EMIFA Boot, HPI Boot, or PCI
Boot, etc.). FASTBOOT determines if the PLL is enabled during boot to speed up the boot process.
The combination of AEM[2:0] and PLLMS[2:0] is used by bootloader code to determine the PLL multiplier
used during fastboot modes (FASTBOOT = 1).
The DM6433 boot modes are grouped into three categories—Non-Fastboot Modes, Fixed-Multiplier
Fastboot Modes, and User-Select Multiplier Fastboot Modes.
•
Non-Fastboot Modes (FASTBOOT = 0): The device operates in default PLL bypass mode during
boot. The Non-Fastboot bootmodes available on the DM6433 are shown in Table 3-5.
•
Fixed-Multiplier Fastboot Modes (FASTBOOT = 1, AEM[2:0] = 001b): The bootloader code speeds
up the device during boot according to the fixed PLL multipliers. The Fixed-Multiplier Fastboot
bootmodes available on the DM6433 are shown in Table 3-6.
Note: The PLLMS[2:0] configurations have no effect on the Fixed-Multiplier Fastboot Modes, as these
pins function as AEAW[2:0] to select the EMIFA address width when AEM[2:0] = 001b.
•
User-Select Multiplier Fastboot Modes (FASTBOOT = 1, AEM[2:0] = 000b,011b,100b,101b): The
bootloader code speeds up the device during boot. The PLL multiplier is selected by the user via the
PLLMS[2:0] pins. The User-Select Multiplier Fastboot bootmodes available on the DM6433 are shown
in Table 3-7.
All other modes not shown in these tables are reserved and invalid settings.

As shown in Table 3-5, Table 3-6, and Table 3-7, at device reset the Boot Controller defaults the
DSPBOOTADDR to one of two values based on the boot mode selected. In all boot modes, the C64x+ is
immediately released from reset and begins executing from address location indicated in
DSPBOOTADDR.
•
Internal Bootloader ROM (0x0010 0000): For most boot modes, the DSPBOOTADDR defaults to the
internal Bootloader ROM so that the DSP can immediately execute the bootloader code in the internal
ROM. The bootloader code decodes the captured BOOTMODE, FASTBOOT, PCIEN, default AEM
(DAEM), and PLLMS information (in the BOOTCFG register) to determine the proper boot operation.
Note: For all boot modes that default to DSPBOOTADDR = 0x0010 0000, the bootloader code
disables all C64x+ cache (L2, L1P, and L1D) so that upon exit from the bootloader code, all C64x+
memories are configured as all RAM. If cache use is required, the application code must explicitly
enable the cache. For more information on boot modes, see Section 3.4.1, Boot Modes. For more
information on the bootloader, see the Using the TMS320DM643x Bootloader Application Report
(literature number SPRAAG0).
•
EMIFA Chip Select Space 2 (0x4200 0000): The EMIFA ROM Direct Boot in PLL Bypass Mode
(BOOTCFG settings BOOTMODE[3:0] = 0100b, FASTBOOT = 0) is the only exception where the
DSPBOOTADDR defaults to the EMIFA Chip Select Space 2. The DSP begins execution directly from
the external ROM at this EMIFA space.
For more information how the bootloader code handles each boot mode, see Using the TMS320DM643x
Bootloader Application Report (literature number SPRAAG0).
3.4.1.1 FASTBOOT
When DM6433 exits pin reset (RESET or POR released), the PLL Controllers (PLLC1 and PLLC2) default
to PLL Bypass Mode. This means the PLLs are disabled, and the MXI/CLKIN clock input is driving the
chip. All the clock domain divider ratios discussed in Section 6.3.4, DM6433 Power and Clock Domains,
still apply. For example, assume an MXI/CLKIN frequency of 27 MHz—meaning the internal clock source
for EMIFA is at CLKDIV3 domain = 27 MHz/3 = 9 MHz, a very slow clock. In addition, the EMIFA registers
are reset to the slowest configuration which translates to very slow peripheral operation/boot.
To optimize boot time, the user should reprogram clock settings via the PLLC as early as possible during
the boot process. The FASTBOOT pin facilitates this operation by allowing the device to boot at a faster
clock rate.
Except for the EMIFA ROM Direct Boot in PLL Bypass Mode (BOOTCFG settings BOOTMODE[3:0] =
0100b, FASTBOOT = 0), all other boot modes default to executing from the Internal Bootloader ROM. The
first action that the bootloader code takes is to decode the boot mode. If the FASTBOOT option is
selected (BOOTCFG.FASTBOOT = 1), the bootloader software begins by programming the PLLC1
(System PLLC) to PLL Mode to give the device a slightly faster operation before fetching code from
external devices. The exact PLL multiplier that the bootloader uses is determined by the AEM[2:0] and
PLLMS[2:0] settings, as shown in Table 3-6 and Table 3-7.
Some boot modes must be accompanied with FASTBOOT = 1 so that the corresponding peripheral can
run at a reasonable rate to communicate to the external device(s). This includes PCI boot.
Note: PLLC2 still stays in PLL Bypass Mode, the bootloader does not reconfigure it.

3.4.1.2 Selecting FASTBOOT PLL Multiplier
Table 3-6, Table 3-7, and Table 3-8 show the PLL multipliers used by the bootloader code during fastboot
(FASTBOOT = 1) and the resulting device frequency. The user is responsible for selecting the bootmode
with the appropriate PLL multiplier for their MXI/CLKIN clock source so that the device speed and PLL
frequency range requirements are met. For the PLLC1 Clock Frequency Ranges, see Table 6-15, PLLC1
Clock Frequency Ranges in Section 6.7.1, PLL1 and PLL2.
The following are guidelines for PLL output frequency and device speed (frequency):
•
PLL Output Frequency: (PLLOUT = CLKIN frequency * boot PLL Multiplier) must stay within the
PLLOUT frequency range in Table 6-15, PLLC1 Clock Frequency Ranges.
•
Device Frequency: (SYSCLK1) calculated from Table 3-6 and Table 3-7 must not exceed the
SYSCLK1 maximum frequency in Table 6-15, PLLC1 Clock Frequency Ranges.
For example, for a 600-MHz device with a CLKIN = 27 MHz, in order to stay within the PLLOUT
frequency range and SYSCLK1 maximum frequency from Table 6-15, PLLC1 Clock Frequency
Ranges, the user must select a boot mode with a PLL1 multiplier between x15 and x22.
3.4.1.3 EMIFA Boot Modes
As shown in Table 3-5, Table 3-6, and Table 3-7, there are different types of EMIFA Boot Modes. This
subsection summarizes these types of EMIFA boot modes. For further detailed information, see the Using

3.4.1.4 Serial Boot Modes (I2C, UART[UART0], SPI[McBSP0])
This subsection discusses how the bootloader configures the clock dividers for the serial boot modes—I2C
boot, UART boot, and SPI boot.
3.4.1.4.1 I2C Boot
If FASTBOOT = 0, then I2C Boot (BOOTMODE = 0101) is performed in Standard-Mode (up-to 100 kbps).
If FASTBOOT = 1, then I2C Boot is performed in Fast-Mode (up-to 400 kbps). The actual I2C data
transfer rate is dependent on the MXI/CLKIN frequency.
This is how the bootloader programs the I2C:
•
I2C Boot in Fast-Mode (BOOTMODE[3:0] = 0101b, FASTBOOT = 1)
–
–
I2C register settings: ICPSC.IPSC = 210, ICCLKL.ICCL = 810, ICCKH.ICCH = 810
Resulting in the following I2C prescaled module clock frequency (internal I2C clock):
•
(CLKIN frequency in MHz) / 3
–
Resulting in the following I2C serial clock (SCL):
•
•
•
SCL frequency (in kHz) = (CLKIN frequency in MHz) / 78 * 1000
SCL low pulse duration (in µs) = 39 / (CLKIN frequency in MHz)
SCL high pulse duration (in µs) = 39 / (CLKIN frequency in MHz)
•
I2C Boot in Standard-Mode (BOOTMODE[3:0] = 0101b, FASTBOOT = 0)
–
–
I2C register settings: ICPSC.IPSC = 210, ICCLKL.ICCL = 4510, ICCKH.ICCH = 4510
Resulting in the following I2C prescaled module clock frequency (internal I2C clock):
•
(CLKIN frequency in MHz) / 3
–
Resulting in the following I2C serial clock (SCL):
•
•
•
SCL frequency (in kHz) = (CLKIN frequency in MHz) / 300 * 1000
SCL low pulse duration (in µs) = 150 / (CLKIN frequency in MHz)
SCL high pulse duration (in µs) = 150 / (CLKIN frequency in MHz)
Note: The I2C peripheral requires that the prescaled module clock frequency must be between 7 MHz
and 12 MHz. Therefore, the I2C boot is only available for MXI/CLKIN frequency between 21 MHz and
30 MHz.
For more details on the I2C periperhal configurations and clock requirements, see the TMS320DM643x
DMP Inter-Integrated Circuit (I2C) Peripheral User’s Guide (literature number SPRU991).

3.4.1.4.2 UART Boot
For UART Boot (BOOTMODE[3:0] = 1000b or 1110b), the bootloader programs the UART0 peripheral as
follows:
•
•
UART0 divisor is set to 1510
Resulting in this UART0 baud rate in kilobit per second (kbps):
–
(CLKIN frequency in MHz) * 1000 / (15 * 16)
The user is responsible for ensuring the resulting baud rate is appropriate for the system. The UART0
divisor (/15) is optimized for CLKIN frequency between 27 to 29 MHz to stay within 5% of the 115200-bps
baud rate.
For more details on the UART peripheral configurations and clock generation, see the TMS320DM643x
DMP Universal Asynchronous Receiver/Transmitter (UART) User's Guide (literature number SPRU997).
3.4.1.4.3 SPI Boot
Both 16-bit address SPI Boot (BOOTMODE = 0110) and 24-bit address SPI boot are performed through
the McBSP0 peripheral. The bootloader programs the McBSP0 peripheral as follows:
•
•
McBSP0 register settings: SRGR.CLKGDV = 210
Resulting in this SPI serial clock frequency:
–
(SYSCLK3 frequency in MHz) / 3
SYSCLK3 frequency = SYSCLK1 frequency / 6. SYSCLK1 frequency during boot can be found in
Table 3-5, Table 3-6, Table 3-7, and/or Table 3-8 based on the boot mode selection.
For example, if BOOTMODE[3:0] = 0110b, FASTBOOT = 1, the MXI/CLKIN frequency = 27 MHz,
AEM[2:0] = 000b, PLLMS[2:0] = 100b, the combination of Table 3-7 and Table 3-8 indicates that the
device frequency (SYSCLK1) is CLKIN x 22 / 2 = 297 MHz. This means SYSCLK3 frequency is
297 / 6 = 49.5 MHz, resulting in SPI serial clock frequency of 49.5 / 3 = 16.5 MHz.
3.4.1.5 Host Boot Modes
The DM6433 supports two types of host boots—PCI Boot or HPI Boot.
The PCI Boot (BOOTMODE[3:0] = 0001b or 0010b, PCIEN = 1) is only available in fastboot
(FASTBOOT = 1), as shown in Table 3-6 and Table 3-7.
The HPI Boot is available in fastboot and non-fastboot, as shown in Table 3-5, Table 3-6, and Table 3-7.
Note: The HPI HSTROBE inactive pulse duration timing requirement [tw(HSTBH)] is dependent on the HPI
internal clock source (SYSCLK3) frequency (see Section 6.13.3, HPI Electrical Data/Timing). The external
host must be aware of the SYSCLK3 frequency during boot to ensure the HSTROBE pulse duration
timing requirement is met.

3.4.2.2 BOOTCMPLT Register
If the bootloader code detects an error during boot, it records the error status in the Boot Complete
(BOOTCMPLT) register.
In addition, the BOOTCMPLT register is used for communication between the external host and the
bootloader code during a Host Boot (HPI Boot or PCI Boot). Once the external host has completed boot, it
must perform the following communication with the bootloader code:
•
Write the desired 32-bit CPU starting address in the DSPBOOTADDR register (see Section 3.4.2.3,
DSPBOOTADDR Register).
•
Write a ‘1’ to the Boot Complete (BC) bit field in the BOOTCMPLT register to indicate that the host has
completed booting this device.
Once the bootloader code detects BC = 1, it directs the CPU to begin executing from the
DSPBOOTADDR register.
The BOOTCMPLT register is reset by any device-level global reset. For the list of device-level global
resets, see Section 6.5, Reset.

3.4.2.3 DSPBOOTADDR Register
The DSP Boot Address (DSPBOOTADDR) register contains the starting address for the C64x+ CPU.
Whenever the C64x+ is released from reset, it begins executing from the location pointed to by
DSPBOOTADDR register. For Host boots (HPI Boot or PCI Boot), the DSPBOOTADDR register is also
used for communication between the Host and the bootloader code during boot.

For the boot mode selections, see Table 3-5, Non-Fastboot Modes; Table 3-6, Fixed-Multiplier
Fastboot Modes; and Table 3-7, User-Select Multiplier Fastboot Modes.
For Non-Host Boot Modes, software can leave the DSPBOOTADDR register at default.
For Host Boots (HPI Boot or PCI Boot), the DSPBOOTADDR register is also used for communication
between the Host and the bootloader code during boot. For Host Boots, the DSPBOOTADDR register
defaults to Internal Bootloader ROM, and the C64x+ CPU is immediately released from reset so that it can
begin executing the bootloader code in this internal ROM. The bootloader code waits for the Host to boot
the device. Once the Host is done booting the device, it must write a new starting address into the
DSPBOOTADDR register, and follow with writing BOOTCMPLT.BC = 1 to indicate the boot is complete.
As soon as the bootloader code detects BOOTCMPLT.BC = 1, it instructs the CPU to jump to this new
DSPBOOTADDR address. At this point, the CPU continues the rest of the code execution starting from
the new DSPBOOTADDR location and the boot is completed.

For proper device operation, external pullup/pulldown resistors may be required on these device boot and
configuration pins. For discussion situations where external pullup/pulldown resistors are required, see
Section 3.9.1, Pullup/Pulldown Resistors.
Note: Except for PCIEN, all other DM6433 configuration inputs (BOOTMODE[3:0], FASTBOOT,
AEAW[2:0]/PLLMS[2:0] and AEM[2:0]) are multiplexed with other functional pins. These pins function as
device boot and configuration pins only during device reset. The user must take care of any potential data
contention in the system. To help avoid system data contention, the DM6433 puts these configuration pins
into a high-impedance state (Hi-Z) when device reset (RESET or POR) is asserted, and continues to hold
them in a high-impedance state until the internal global reset is removed; at which point, the default
peripheral (either GPIO or EMIFA based on default of AEM[2:0]) will now control these pins.
All of the device boot and configuration pin settings are captured in the corresponding bit fields in the
BOOTCFG register (see Section 3.4.2.1).
The following subsections provide more details on the device configurations determined at device reset:
AEM, AEAW/PLLMS, and PCIEN.
3.5.1.1 EMIFA Pinout Mode (AEM[2:0])
To support different usage scenarios, the DM6433 provides intricate pin multiplexing between the EMIFA
and other peripherals. The PINMUX0.AEM register bit field in the System Module determines the EMIFA
Pinout Mode. The AEM[2:0] pins only select the default EMIFA Pinout Mode. It is latched at device reset
de-assertion (high) into the BOOTCFG.DAEM bit field. The AEM[2:0] value also sets the default of the
PINMUX0.AEM bit field. While the BOOTCFG.DAEM bit field shows the actual latched value and cannot
be modified, the PINMUX0.AEM value can be changed by software to modify the EMIFA Pinout Mode.
Note: The AEM[2:0] value does not affect the operation of the EMIFA module itself. It only affects which
EMIFA pins are brought out to the device pins. For more details on the AEM settings, see Section 3.7,
Multiplexed Pin Configurations.
In addition, for Fastboot modes (FASTBOOT = 1), the bootloader code determines the PLL1 multiplier
based on the default settings of AEM[2:0] and PLLMS[2:0]. For more details, see Section 3.4.1.1,
Fastboot, and Section 3.5.1.2, EMIFA Address Width Select (AEAW) and FASTBOOT PLL Multiplier
Select (PLLMS).
3.5.1.2 EMIFA Address Width Select (AEAW) and FASTBOOT PLL Multiplier Select (PLLMS)
The AEAW[2:0]/PLLMS[2:0] pins serve two functional purposes (AEAW or PLLMS), depending on the
FASTBOOT and AEM settings. The AEAW[2:0]/PLLMS[2:0] pins are latched at device reset de-assertion
(high) and captured in the BOOTCFG.PLLMS bit field. This value also sets the default of the
PINMUX0.AEAW field.
While the BOOTCFG.PLLMS field shows the actual latched value and cannot be modified, the
PINMUX0.AEAW value can be changed by software to modify the EMIFA pinout.
AEAW as EMIFA Address Width Select (AEAW)
If AEM[2:0] = 001b [8-bit EMIFA (Async) Pinout Mode 1], the AEAW[2:0]/PLLMS[2:0] pins serve as AEAW
to set the default of the EMIFA Address Width Selection.
On DM6433, only AEAW = 100b is supported. If AEM[2:0] = 001b [8-bit EMIFA (Async) Pinout Mode 1],
AEAW must be set to 100b to select full addres width for EMIFA. For other EMIFA Pinout Modes (AEM
not 001b), AEAW is not applicable in determining the EMIFA address width.
Note: AEAW[2:0] value does not affect the operation of the EMIFA module itself.

For more information on boot modes and the FASTBOOT PLL multiplier selection, see Section 3.4.1, Boot
Modes.
3.5.1.3 PCI Enable (PCIEN)
The PCIEN configuration pin determines if the PCI peripheral is used on this device. If PCIEN = 1
indicating the PCI is used, then the PCI multiplexed pins default to PCI functions, and the pins’
corresponding internal pullup/pulldown resistors are disabled. If PCIEN = 0 indicating the PCI is not used,
then the PCI muxed pins default to non-PCI functions, and the pins’ corresponding internal
pullup/pulldown resistors are enabled.
The PCIEN setting is captured and stored in the BOOTCFG.DPCIEN bit field, and also in the
PINMUX1.PCIEN bit field. These values cannot be changed by software. Furthermore, for proper device
operation, the user must hold the desired setting at the PCIEN pin throughout device operation.

3.6 Configurations After Reset
The following sections provide details on configuring the device after reset.
Multiplexed pins are configured both at and after reset. Section 3.5.1, Device and Peripheral
Configurations at Device Reset, discusses multiplexed pin control at reset. For more details on multiplexed
pins control after reset, see Section 3.7 , Multiplexed Pin Configurations.
3.6.1 Switch Central Resource (SCR) Bus Priorities
Prioritization within the Switched Central Resource (SCR) is programmable for each master. The register
bit fields and default priority levels for DM6433 bus masters are shown in Table 3-13, DM6433 Default Bus
Master Priorities. The priority levels should be tuned to obtain the best system performance for a particular
application. Lower values indicate higher priority. For most masters, their priority values are programmed
at the system level by configuring the MSTPRI0 and MSTPRI1 registers. Details on the MSTPRI0/1
registers are shown in Figure 3-6 and Figure 3-7. The C64x+, VPSS, and EDMA masters contain registers
that control their own priority values.

3.7 Multiplexed Pin Configurations
DM6433 makes extensive use of pin multiplexing to accommodate a large number of peripheral functions
in the smallest possible package, providing ultimate flexibility for end applications.
The Pin Multiplex Registers PINMUX0 and PINMUX1 in the System Module are responsible for controlling
all pin multiplexing functions on the DM6433. The default setting of some of the PINMUX0 and PINMUX1
bit fields are configured by configuration pins latched at reset (see Section 3.5.1, Device and Peripheral
Configurations at Device Reset). After reset, software may program the PINMUX0 and PINMUX1 registers
to switch pin functionalities.
The following peripherals have multiplexed pins: VPSS (VPBE), EMIFA, PCI, HPI, VLYNQ, EMAC,
McASP0, McBSP0, PWM0, PWM1, PWM2, Timer0, Timer1, UART0, and GPIO.
The device is divided into the following Pin Multiplexed Blocks (Pin Mux Blocks):
•
EMIFA/VPSS Block: VPSS (VPBE), EMIFA, part of PCI, GPIO. This block is further subdivided into
these sub-blocks:
–
–
–
–
Sub-Block 0: part of EMIFA (data, address, control), part of PCI, and GPIO
Sub-Block 1: VPBE (VENC), part of EMIFA (data, address, control), and GPIO
Sub-Block 2: part of EMIFA (control signals EM_WAIT/(RDY/BSY), EM_OE, and EM_WE)
Sub-Block 3: part of EMIFA (address EM_A[12:5]), part of PCI, and GPIO
•
•
•
•
Host Block: HPI, VLYNQ, EMAC, part of PCI, and GPIO
PCI Data Block: part of PCI
GPIO Block: part of PCI and GPIO
Serial Port Block: McBSP0, McASP0, and GPIO. This block is further sub-divided into sub-blocks.
–
–
Serial Port Sub-Block 0: McBSP0, part of McASP0, and GPIO
Serial Port Sub-Block 1: part of McASP0, and GPIO
•
•
•
•
•
•
UART0 Flow Control Block: UART0 flow control, PWM0, and GPIO
UART0 Data Block: UART0 data and GPIO
Timer0 Block: Timer0 and McBSP0 CLKS pins
Timer1 Block: Timer1
PWM1 Block: PWM1 and GPIO
CLKOUT Block: CLKOUT0, PWM2, and GPIO
As shown in the list above, the PCI, McBSP0, and UART0 peripherals span multiple Pin Mux Blocks. To
use these peripherals, they must be selected in all relevant Pin Mux Blocks. For more details, see
Section 3.7.3, Pin Multiplexing Details, and Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux
Blocks.
Note: There is no actual pin multiplexing in EMIFA/VPSS Sub-Block 2 and the PCI Data Block. However
these are still considered "pin mux blocks" because they contain part of the pins necessary for EMIFA and
PCI, respectively.
A high level view of the Pin Mux Blocks is shown in Figure 3-11. In each Pin Mux Block, the
PINMUX0/PINMUX1 default settings are underlined.
Note: Some default pin functions are determined by configuration pins (PCIEN, AEAW[2:0], AEM[2:0]);
therefore, more than one configuration setting can serve as default based on the configuration pin settings
latched at device reset.

3.7.2 Pin Muxing Selection After Reset
The PINMUX0 and PINMUX1 registers in the System Module allow software to select the pin functions in
the Pin Mux Blocks. The pin control of some of the Pin Mux Blocks requires a combination of
PINMUX0/PINMUX1 bit fields. For more details on the combination of the PINMUX bit fields that control
each muxed pin, see Section 3.7.3.1, Multiplexed Pins on DM6433.
This section only provides an overview of the PINMUX0 and PINMUX1 registers. For more detailed
discussion on how to program each Pin Mux Block, see Section 3.7.3, Pin Multiplexing Details.
3.7.2.1 PINMUX0 Register Description
The Pin Multiplexing 0 Register (PINMUX0) controls the pin function in the EMIFA/VPSS Block. The
PINMUX0 register format is shown in Figure 3-12 and the bit field descriptions are given in Table 3-19.
Some muxed pins are controlled by more than one PINMUX bit field. For the combination of the PINMUX
bit fields that control each muxed pin, see Section 3.7.3.1, Multiplexed Pins on DM6433. For more
information on EMIFA/VPSS Block pin muxing, see Section 3.7.3.13, EMIFA/VPSS Block Muxing. For the
pin-by-pin muxing control of the EMIFA/VPSS Block, see Section 3.7.3.13.7, EMIFA/VPSS Block
Pin-By-Pin Multiplexing Summary.
Note: In addition to PINMUX0 bit fields, the EMIFA/VPSS Block also requires the PCIEN bit in the Pin
Multiplexing 1 Register (PINMUX1, Section 3.7.2.2) to determine the PCI settings.

3.7.3 Pin Multiplexing Details
This section discusses how to program each Pin Mux Block to select the desired peripheral functions.
The following steps can be used to determine pin muxing suitable for the application:
1. Understand the major configuration choices available for the specific application.
a. Device Major Configuration Choices: Figure 3-11 shown in Section 3.7, Multiplexed Pin
Configurations, provides a high-level view of the device pin muxing and can be used to determine
the possible mix of peripheral options for a specific application.
b. EMIFA/VPSS Block Major Configuration Choices: The EMIFA/VPSS block features extensive pin
multiplexing to accommodate a variety of applications. In addition to Figure 3-11, Section 3.7.3.13,
EMIFA/VPSS Block Muxing, provides more details on the Major Configuration choices for this
block.
2. See Section 3.7.3.1, Multiplexed Pins on DM6433, for a summary of all the multiplexed pins on this
device and the pin mux group they belong to.
3. Refer to the individual pin mux sections (Section 3.7.3.3, Host Block Muxing to Section 3.7.3.13,
EMIFA/VPSS Block Muxing) for pin muxing details for a specific pin mux block.
a. For peripherals that span multiple pin mux blocks, the user must select the appropriate pins for that
peripheral in all relevant pin mux blocks. For more details, see Section 3.7.3.2, Peripherals
Spanning Multiple Pin Mux Blocks .
For details on PINMUX0 and PINMUX1 registers, see Section 3.7.2.
3.7.3.1 Multiplexed Pins on DM6433
Table 3-21 summarizes all of the multiplexed pins on DM6433, the pin mux group for each pin, and the
PINMUX register fields that control the pin. For pin mux details, see the specific pin mux group section
(Section 3.7.3.3, Host Block Muxing to Section 3.7.3.13, EMIFA/VPSS Block Muxing). For a description of
the PINMUX register fields, see Section 3.7.2.

3.7.3.2 Peripherals Spanning Multiple Pin Mux Blocks
Some peripherals span multiple Pin Mux Blocks. To use these peripherals, they must be selected in all of
the relevant Pin Mux Blocks. The following is the list of peripherals that span multiple Pin Mux Blocks:
•
PCI: PCI pins span across the Host Block, EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3, PCI
Data Block, and GPIO Block. To select PCI pins, program PINMUX registers as follows:
–
–
Host Block: PCIEN = 1, HOSTBK = 000
EMIFA/VPSS Block: Select either Major Configuration Option F or G. For more details on the
PINMUX settings associated with Major Configuration Options F or G, see Section 3.7.3.13,
EMIFA/VPSS BLock Muxing.
–
–
PCI Data Block: PCIEN = 1
GPIO Block: PCIEN = 1
•
•
McBSP0: Six McBSP0 pins are located in the Serial Port Sub-Block 0, but the CLKS0 pin is muxed in
the Timer0 Block. To select McBSP0 pins, program PINMUX registers as follows:
–
–
Serial Port Sub-Block 0: SPBK0 = 01
Timer0 Block: If CLKS0 pin is desired, program TIM0BK = 10 or 11.
UART0: The two UART0 data pins are located in the UART0 Data Block, but the two UART0 flow
control pins are located in the UART0 Flow Control Block. To select UART0, program PINMUX
registers as follows:
–
–
UART0 Data Block: UR0BK = 1
UART0 Flow Control Block: If flow control pins are desired, program UR0FCBK = 01.

As discussed in Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux Blocks, PCI pins span across the
following Pin Mux Blocks: Host Block, EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3, PCI Data Block,
and GPIO Block. For proper PCI operation, PCI must be selected in all of these Pin Mux Blocks.

3.7.3.4 PCI Data Block
This block of 3 pins consists of 3 PCI Address/Data pins—AD30, AD28, AD26. The PINMUX1.PCIEN
register field affects the pin functions in the PCI Data Block.
As discussed in Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux Blocks, PCI pins span across the
following Pin Mux Blocks: Host Block, EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3, PCI Data Block,
and GPIO Block. For proper PCI operation, PCI must be selected in all of these Pin Mux Blocks.
The 3 pins in the PCI Data Block are not muxed with any other peripherals. However, the
PINMUX1.PCIEN field controls the internal pullup/pulldown resistors on these pins. For PCI operation
(PCIEN = 1), the internal pullup/pulldown resistors are disabled. If the device does not support PCI
(PCIEN = 0), the internal pullup/pulldown resistors on these pins are enabled so that the user can leave
these pins unconnected on the board.

The EMIFA/VPSS Block is divided into multiple sub-blocks for ultimate flexibility in pin multiplexing to
accommodate a wide variety of applications:
•
•
•
•
Sub-Block 0: multiplexed between EMIFA data/address/control pins, PCI, and GPIO.
Sub-Block 1: multiplexed between VPBE, EMIFA data/address/control pins, and GPIO.
Sub-Block 2: no multiplexing. EMIFA control pins EM_WAIT/(RDY/BSY), EM_OE, EM_WE.
Sub-Block 3: multiplexed between EMIFA address pins EM_A[12:6], PCI, and GPIO.
As discussed in Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux Blocks, PCI pins span across the
following Pin Mux Blocks: Host Block, EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3, PCI Data Block,
and GPIO Block. For proper PCI operation, PCI must be selected in all of these Pin Mux Blocks.
The EMBK0, EMBK1, EMBK2, EMBK3 fields in the VDD3P3V_PWDN register determine the power state

(1) For additional pin mux details for each Sub-Block, see Table 3-44 through Table 3-48, EMIFA/VPSS Sub-Block 1 Configuration Choices.
(2) PCI pins span across multiple Pin Mux Blocks (Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux Blocks). This table only refers to
the PCI pins in the EMIFA/VPSS Block.
(3) If PINMUX0.AEM = 001 or 011, it is not possible to get LCD_FIELD pin for VPBE.
As shown in Table 3-42, the major configuration choices of the EMIFA/VPSS Block are determined by the
following PINMUX register fields:
•
•
PINMUX1 register field PCIEN
PINMUX0 register fields AEM and VENCSEL
Based on the peripheral needs, select from the major configuration options in this block: Major

The following is an example on how to read Table 3-42. For example, the "PINMUX Selection Fields"
columns indicate that Major Configuration Choice B is selected through setting PINMUX1.PCIEN = 0,
PINMUX0.AEM = 1, and VENCSEL = 0 or 1 (based on the system's VPBE requirement). The "Resulting
Peripherals/Pins" columns indicate that Major Configuration Option B can support the following
combination of pin functions:
•
•
No PCI pins
Pins for 8-bit EMIFA (Async or NAND) function. The number of address pins supported provide
16MByte address reach per EMIFA Chip Select (CS) space.
•
Pins for up to 8-bit VPBE. If 8-bit VPBE (VENCSEL = 1) is selected, the user may have 0 to 4 GPIO
pins. Exact detail on number of GPIO pins and VPBE control pins is further determined by other
PINMUX0 settings discussed in the EMIFA/VPSS Sub-Block 1 Configuration Choices.
•
11 GPIO pins (GP[54:52, 43:36]) from EMIFA/VPSS Sub-Block 0.
After using Table 3-42 to select the Major Configuration Option for the EMIFA/VPSS Block, proceed to
select the detailed pin choices in the EMIFA/VPSS Sub-Blocks.
3.7.3.13.3 EMIFA/VPSS Sub-Block 0 Configuration Choices
The pins in the EMIFA/VPSS Sub-Block 0 are muxed between part of EMIFA, part of PCI, and GPIO. The
pin functions in the EMIFA/VPSS Sub-Block 0 are determined by the following PINMUX register fields:
•
•
PINMUX1.PCIEN
PINMUX0:AEM, AEAW (must be set to 100b)
Once the Major Configuration Option for the EMIFA/VPSS Block has been selected (see
Section 3.7.3.13.2, EMIFA/VPSS Block Major Configuration Choices), no further actions are necessary to
refine the EMIFA/VPSS Sub-Block 0 pin selection. For instructions on the procedures to configure the
EMIFA/VPSS Block, see Section 3.7.3.13.1, EMIFA/VPSS Block Pin Selection Procedure.
Table 3-43 summarizes the pin selections in the EMIFA/VPSS Sub-Block 0 based on the PINMUX
selections.

C, D, E, F, or G), the user can now use Table 3-44 through Table 3-48 to refine the Sub-Block 1 pin
selections.
1. Go to the table with the Major Configuration Option chosen from Table 3-42.
2. Each Major Configuration Option is further divided down into multiple Minor Configuration Options.
Select a Minor Configuration Option that best suits the application need.
3. Within the chosen Minor Configuration Option, further refine the detailed pin configurations by selecting
the settings of PINMUX0 fields VENCSEL, RGBSEL, CS3SEL, CS4SEL, CS5SEL, and VPBECKEN.

As shown in Table 3-44 through Table 3-48, the configuration choices of the EMIFA/VPSS Sub-Block 1
are determined by the following PINMUX register fields:
•
PINMUX0 register fields AEM, VENCSEL, RGBSEL, CS3SEL, CS4SEL, CS5SEL, and VPBECKEN.
The following is an example on how to read Table 3-44 through Table 3-48 using Sub-Block 1 Minor
Configuration G2 as an example:
•
•
The PINMUX Selection Fields columns indicate that Sub-Block 1 Minor Configuration Option G2 is
selected through setting PINMUX0 fields to AEM = 5, VENCSEL = 1, RGBSEL = 0 or 1 (based on
whether the VPBE LCD_FIELD pin is needed), CS3SEL = 0/1/2 (based on the desired pin choice),
CS4SEL = 0/1/2 (based on the desired pin choice), CS5SEL = 0/1/2 (based on the desired pin choice),
and VPBECKEN = 0/1 (based on whether VPBE VPBECLK is needed).
The Resulting Peripherals/Pins columns show the functional pins resulting from the PINMUX setting.
For example, PINMUX0.VENCSEL = 1 gives you the VCLK and YOUT[7:0] pins for the VPBE, in
addition to EM_D[7:0] pins for the EMIFA. PINMUX0.RGBSEL = 1 gives you the LCD_FIELD pin for
the VPBE, along with EM_A[2:1] and EM_CS2 for the EMIFA, and 4 GP pins.

3.7.3.13.5 EMIFA/VPSS Sub-Block 2 Configuration Choices
The 3 pins in the EMIFA/VPSS Sub-Block 2 are standalone (non-multiplexed) pins. They always function
as EMIFA control pins EM_WAIT/(RDY/BSY), EM_OE, and EM_WE. No pin mux selection is necessary
for this Sub-Block.
3.7.3.13.6 EMIFA/VPSS Sub-Block 3 Configuration Choices
The 8 pins in the EMIFA/VPSS Sub-Block 3 are multiplexed between:
•
•
•
EMIFA Address Pins EM_A[12:5]
PCI pins: PCBE3, PIDSEL, AD[24:19]
GPIO pins GP[96:89]
The pin functions in the EMIFA/VPSS Sub-Block 3 are determined by the following PINMUX register
fields:
•
•
PINMUX1.PCIEN
PINMUX0.AEM
Once the Major Configuration Option for the EMIFA/VPSS Block (see Section 3.7.3.13.2, EMIFA/VPSS
Block Major Configuration Choices) is chosen, no further actions are necessary to refine the EMIFA/VPSS
Sub-Block 3 pin selection. For instructions on configuring the EMIFA/VPSS Block, see Section 3.7.3.13.1,
EMIFA/VPSS Block Pin Selection Procedure.
Table 3-49 summarizes the pin selections in the EMIFA/VPSS Sub-Block 3 based on the PINMUX
selections.

•
The PINMUX Selection Fields columns indicate that Sub-Block 3 Major Configuration Option C is
selected through PINMUX1.PCIEN = 0 and PINMUX0.AEM = 3.
•
The Resulting Peripherals/Pins columns show the functional pins resulting from the PINMUX setting. In
Major Configuration C, the user gets EMIFA address pins EM_A[12:5] from Sub-Block 3.

3.7.3.13.7 EMIFA/VPSS Block Pin-By-Pin Multiplexing Summary
This section summarizes the EMIFA/VPSS Block muxing on a pin-by-pin basis. It provides an alternative
view to pin muxing in the EMIFA/VPSS Block. This section should only be used after following the
procedures listed in Section 3.7.3.13.1 to determine the actual EMIFA/VPSS Configuration Option for the
application need.
Table 3-50 shows the pin multiplexing control for each pin in the EMIFA/VPSS Sub-Block 0. These are the
fields in the PINMUX0 and PINMUX1 registers that control the multiplexing in this sub-block:
•
•
PINMUX0: AEM and AEAW
PINMUX1: PCIEN
Table 3-51 shows the pin multiplexing control for each pin in the EMIFA/VPSS Sub-Block 1. These are the
fields in the PINMUX0 register that control the multiplexing in this sub-block:

3.8 Device Initialization Sequence After Reset
Software should follow this initialization sequence after coming out of device reset.
1. Complete the boot sequence as needed. For more details on the boot sequence, see the Using the
TMS320DM643x Bootloader Application Report (literature number SPRAAG0).
2. If the device is not already at the desired operating frequency, program the PLL Controllers (PLLC1
and PLLC2) to configure the device frequency. For details on how to program the PLLC, see the
TMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978).
3. Program PINMUX0 and PINMUX1 registers to select device pin functions. For more details on
programming the PINMUX0 and PINMUX1 registers to select device pin functions, see Section 3.7,
Multiplexed Pin Configurations.
Note: If EMAC operation is desired, the EMAC must be placed in reset before programming
PINMUX1.HOSTBK to select EMAC pins.
4. Program the VDD3P3V_PWDN register to power up the necessary I/O pins. For more details on
programming the VDD3P3V_PWDN register, see Section 3.2, Power Considerations.
5. As needed by the application, program the following System Module registers when there are no active
transactions on the respective peripherals:
a. HPICTL (Section 3.6.2.1, HPI Control Register): applicable for HPI only if a different host burst
write timeout value from default is desired.
b. TIMERCTL (Section 3.6.2.2, Timer Control Register): applicable for Timer0 and Watchdog Timer2
only.
c. EDMATCCFG (Section 3.6.2.3, EDMA TC Configuration Register): applicable for EDMA only. The
recommendation is to leave the EDMATCCFG register at its default.
d. VPSS_CLKCTL (Section 3.3.1.2.1, VPSS Clocks): applicable for VPSS only.
6. Program the Power and Sleep Controller (PSC) to enable the desired peripherals. For details on how
to program the PSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literature
number SPRU978).
7. Program the Switched Central Resource (SCR) bus priorities for the master peripherals
(Section 3.6.1). This must be configured when there are no active transactions on the respective
peripherals:
a. Program the MSTPRI0 and MSTPRI1 registers in the System Module. These registers can be
programmed before or after the respective peripheral is enabled by the PSC in step 6.
b. Program the EDMACC QUEPRI register, the C64x+ MDMAARBE.PRI field, and the VPSS PCR
register. These registers can only be programmed after the respective peripheral is enabled by the
PSC in step 6.
8. Configure the C64x+ Megamodule and the peripherals.
a. For details on C64x+ Megamodule configuration, see the TMS320C64x+ DSP Megamodule
Reference Guide (literature number SPRU871).
Special considerations: Bootloader disables C64x+ cache—For all boot modes that default to
DSPBOOTADDR = 0x0010 0000 (i.e., all boot modes except the EMIFA ROM Direct Boot,
BOOTMODE[3:0] = 0100, FASTBOOT = 0), the bootloader code disables all C64x+ cache (L2,
L1P, and L1D) so that upon exit from the bootloader code, all C64x+ memories are configured as
all RAM (L2CFG.L2MODE = 0h, L1PCFG.L1PMODE = 0h, and L1DCFG.L1DMODE = 0h). If cache
use is required, the application code must explicitly enable the cache. For more information on boot
modes, see Section 3.4.1, Boot Modes. For more information on the bootloader, see the Using the
TMS320DM643x Bootloader Application Report (literature number SPRAAG0).

b. Peripherals configuration: see the respective peripheral user’s guide.
Special considerations: DDR2 memory controller—the Peripheral Bus Burst Priority Register
(PBBPR) should be programmed to ensure good DDR2 throughput and to prevent command
starvation (prevention of certain commands from being processed by the DDR2 memory controller).
For more details, see the TMS320DM643x DMP DDR2 Memory Controller User’s Guide (literature
number SPRU986). A hex value of 0x20 is recommended for the PBBPR PR_OLD_COUNT field to
provide a good DSP performance and still allow good utilization by other modules.

3.9 Debugging Considerations
3.9.1 Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the DM643x DMP device always be at a valid logic
level and not floating. This may be achieved via pullup/pulldown resistors. The DM643x DMP features
internal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless
otherwise noted, for external pullup/pulldown resistors.
An external pullup/pulldown resistor needs to be used in the following situations:
•
Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external
pullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desired
value/state.
•
•
Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external
pullup/pulldown resistor to pull the signal to the opposite rail.
EMIFA Chip Select Outputs: On DM6433, the EMIFA chip select pins (EM_CS2, EM_CS3, EM_CS4,
and EM_CS5) feature an internal pulldown (IPD) resistor. If these pins are connected and used as an
EMIFA chip select signal, for proper device operation, an external pullup resistor must be used to
ensure the EM_CSx function defaults to an inactive (high) state.
For the boot and configuration pins (listed in Table 2-5, Boot Terminal Functions), if they are both routed
out and 3-stated (not driven), it is strongly recommended that an external pullup/pulldown resistor be
implemented. Although, internal pullup/pulldown resistors exist on these pins and they may match the
desired configuration value, providing external connectivity can help ensure that valid logic levels are
latched on these device boot and configuration pins. In addition, applying external pullup/pulldown
resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in
switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
•
Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure
to include the leakage currents of all the devices connected to the net, as well as any internal pullup or
pulldown resistors.
•
Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of
all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all
inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of
the limiting device; which, by definition, have margin to the VIL and VIH levels.
•
•
Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the net
will reach the target pulled value when maximum current from all devices on the net is flowing through
the resistor. The current to be considered includes leakage current plus, any other internal and
external pullup/pulldown resistors on the net.
For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance
value of the external resistor. Verify that the resistance is small enough that the weakest output buffer
can drive the net to the opposite logic level (including margin).
•
•
Remember to include tolerances when selecting the resistor value.
For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems, a 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria.
Users should confirm this resistor value is correct for their specific application.
For most systems, a 20-kΩ resistor can be used to compliment the IPU/IPD on the boot and configuration
pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific
application.
For more detailed information on input current (II), and the low-/high-level input voltages (VIL and VIH) for
the DM643x DMP, see Section 5.3, Electrical Characteristics Over Recommended Ranges of Supply
Voltage and Operating Temperature.

4 System Interconnect
On the DM6433 device, the C64x+ Megamodule, the EDMA3 transfer controllers, and the system
peripherals are interconnected through a switch fabric architecture (see Figure 4-1). The switch fabric is
composed of multiple switched central resources (SCRs) and multiple bridges. The SCRs establish
low-latency connectivity between master peripherals and slave peripherals. Additionally, the SCRs provide
priority-based arbitration and facilitate concurrent data movement between master and slave peripherals.
Through an SCR, the DSP subsystem can send data to the DDR2 Memory Controller without affecting a
data transfer between the EMAC and L2 memory. Bridges are mainly used to perform bus-width
conversion as well as bus operating frequency conversion. For example, in Figure 4-1, Bridge 6 performs
a frequency conversion between a bus operating at DSP/3 clock rate and a bus operating at DSP/6 clock
rate. Furthermore, Bridge 5 performs a bus-width conversion between a 64-bit bus and a 32-bit bus.
The C64x+ Megamodule, the EDMA3 transfer controllers (EDMA3TC[2:0]), and the various system
peripherals can be classified into two categories: master peripherals and slave peripherals. Master
peripherals are typically capable of initiating read and write transfers in the system and do not rely on the
EDMA3 or on the CPU to perform transfers to and from them. The system master peripherals include the
C64x+ Megamodule, the EDMA3 transfer controllers, VLYNQ, EMAC, HPI, PCI, and VPSS. Not all master
peripherals may connect to all slave peripherals. The supported connections are designated by "Y" in
Table 4-1.

4.1 System Interconnect Block Diagram
Figure 4-1 displays the DM6433 system interconnect block diagram. The following is a list that helps in
the interpretation of this diagram:
•
•
•
The direction of the arrows indicates either a bus master or bus slave.
The arrow originates at a bus master and terminates at a bus slave.
The direction of the arrows does not indicate the direction of data flow. Data flow is typically
bi-directional for each of the documented bus paths.
•
•
The pattern of each arrow's line indicates the clock rate at which it is operating— i.e., either DSP/3,
DSP/6, or MXI/CLKIN clock rate.
A peripheral may have multiple instances shown in Figure 4-1 for the following reason:
–
The peripheral/module has master port(s) for data transfers, as well as slave port(s) for register
access, data access, and/or memory access. Examples of these peripherals are C64X+
Megamodule, EDMA3, VPSS, VLYNQ, HPI, EMAC, and PCI.

utilization and 50% switching; Timer0 at 100% utilization. At room temperature (25 C) for typical process ZWT devices. The actual
current draw varies across manufacturing processes and is highly application-dependent. DM643x DMP devices are offered in two basic
options: lower-power option and high-performance option. Low-power devices offer lower power consumption across temperature and
voltage when compared with high-performance devices. However, high-performance devices offer higher operating speeds. For more
details on core and I/O activity, high-performance and low-power device power consumption, as well as information relevant to board

NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects must
be taken into account. A transmission line with a delay of 2 ns can be used to produce the desired transmission line effect. The transmission
line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.

Digital Media Processor
SPRS343C–NOVEMBER 2006–REVISED JUNE 2008

TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the
timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given
system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). If
needed, external logic hardware such as buffers may be used to compensate any timing differences.
For the DDR2 memory controller interface, it is not necessary to use the IBIS models to analyze timing
characteristics. TI provides a PCB routing rules solution that describes the routing rules to ensure the
DDR2 memory controller interface timings are met. See the Implementing DDR2 PCB Layout on the
TMS320DM643x DMP DMSoC Application Report (literature number SPRAAL6).
6.2 Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner.
6.3 Power Supplies
For more information regarding TI's power management products and suggested devices to power TI
DSPs, visit www.ti.com/dsppower.
6.3.1 Power-Supply Sequencing
The DM6433 includes one core supply (CVDD), and two I/O supplies—DVDD33 and DVDDR2. To ensure
proper device operation, a specific power-up sequence must be followed. Some TI power-supply devices
include features that facilitate power sequencing—for example, Auto-Track and Slow-Start/Enable
features. For more information on TI power supplies and their features, visit www.ti.com/dsppower.
Here is a summary of the power sequencing requirements:
•
The power ramp order must be DVDD33 before DVDDR2, and DVDDR2 before CVDD—meaning during
power up, the voltage at the DVDDR2 rail should never exceed the voltage at the DVDD33 rail. Similarly,
the voltage at the CVDD rail should never exceed the voltage at the DVDDR2 rail.
•
From the time that power ramp begins, all power supplies (DVDD33, DVDDR2, CVDD) must be stable
within 200 ms. The term "stable" means reaching the recommended operating condition (see
Section 5.2, Recommended Operating Conditions table).
6.3.2 Power-Supply Design Considerations
Core and I/O supply voltage regulators should be located close to the DSP to minimize inductance and
resistance in the power delivery path. Additionally, when designing for high-performance applications
utilizing the DM6433 device, the PC board should include separate power planes for core, I/O, and
ground; all bypassed with high-quality low-ESL/ESR capacitors.
6.3.3 Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to the DSP. These caps need to be close to the DSP, no more than 1.25 cm maximum
distance to be effective. Physically smaller caps are better, such as 0402, but need to be evaluated from a
yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling
capacitors, therefore physically smaller capacitors should be used while maintaining the largest available
capacitance value.
Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the order
of 100 µF) should be furthest away, but still as close as possible. Large caps for each supply should be
placed outside of the BGA footprint.
As with the selection of any component, verification of capacitor availability over the product's production
lifetime should be considered.
For more details on capacitor usage and placement, see the Implementing DDR2 PCB Layout on the
TMS320DM643x DMP DMSoC Application Report (literature number SPRAAL6).

6.3.4 DM6433 Power and Clock Domains
The DM6433 includes one single power domain — the "Always On" power domain. The "Always On"
power domain is always on when the chip is on. The "Always On" domain is powered by the CVDD pins of
the DM6433. All DM6433 modules lie within the "Always On" power domain. Table 6-1 provides a listing of
the DM6433 clock domains.
One primary reference clock is required for the DM6433 device. It can be either a crystal input or driven by
external oscillators. A 27-MHz crystal is recommended for the PLLs, which generate the internal clocks for
the digital media processor (DMP), peripherals, and EDMA3.
The DM6433 architecture is divided into the power and clock domains shown in Table 6-1. Table 6-2 and
Table 6-3 further discuss the clock domains and their ratios. Figure 6-4 shows the Clock Domain block
diagram.

6.3.5 Power and Sleep Controller (PSC)
The Power and Sleep Controller (PSC) controls power by turning off unused power domains or by gating
off clocks to individual peripherals/modules. The DM6433 device only utilizes the clock gating feature of
the PSC for power savings. The PSC consists of a Global PSC (GPSC) and a set of Local PSCs (LPSCs).
The GPSC contains memory mapped registers, PSC interrupt control, and a state machine for each
peripheral/module. An LPSC is associated with each peripheral/module and provides clock and reset
control. The LPSCs for DM6433 are shown in Table 6-4. The PSC Register memory map is given in
Table 6-5. For more details on the PSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide
(literature number SPRU978).

6.4 Enhanced Direct Memory Access (EDMA3) Controller
The EDMA controller handles all data transfers between memories and the device slave peripherals on
the DM6433 device. These data transfers include cache servicing, non-cacheable memory accesses,
user-programmed data transfers, and host accesses. These are summarized as follows:
•
Transfer to/from on-chip memories
–
–
DSP L1D memory
DSP L2 memory
•
Transfer to/from external storage
–
–
–
DDR2 SDRAM
NAND flash

The EDMA supports two addressing modes: constant addressing and increment addressing. On the
DM6433, constant addressing mode is not supported by any peripheral or internal memory. For more
information on these two addressing modes, see the TMS320DM643x DMP Enhanced Direct Memory
Access (EDMA3) Controller User's Guide (literature number SPRU987).
6.4.1 EDMA3 Channel Synchronization Events
The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 6-6 lists the source of EDMA synchronization events associated with each of the programmable
EDMA channels. For the DM6433 device, the association of an event to a channel is fixed; each of the
EDMA channels has one specific event associated with it. These specific events are captured in the
EDMA event registers (ER, ERH) even if the events are disabled by the EDMA event enable registers
(EER, EERH). For more detailed information on the EDMA module and how EDMA events are enabled,
captured, processed, linked, chained, and cleared, etc., see the TMS320DM643x DMP Enhanced Direct
Memory Access (EDMA3) Controller User's Guide (literature number SPRU987).

6.5 Reset
The reset controller detects the different type of resets supported on the DM6433 device and manages the
distribution of those resets throughout the device.
The DM6433 device has several types of device-level global resets - power-on reset, warm reset, and
max reset. Table 6-10 explains further the types of reset, the reset initiator, and the effects of each reset
on the chip. See Section 6.5.9, Reset Electrical Data/Timing, for more information on the effects of each
reset on the PLL controllers and their clocks.
Table 6-10. Device-Level Global Reset Types
TYPE
INITIATOR
EFFECT(s)
POR pin
Global chip reset (Cold reset). Activates the POR signal on chip,
which resets the entire chip including the emulation logic.
The power-on reset (POR) pin must be driven low during power
ramp of the device.
Power-on Reset
(POR)
Device boot and configuration pin are latched.
Resets everything except for the emulation logic. Emulator stays
alive during Warm Reset.
Device boot and configuration pin are latched.
Warm Reset
Max Reset
RESET pin
Same as a Warm Reset, except the DM6433 device boot and
configuration pins are not re-latched.
Emulator, WD Timer (Timer 2)
In addition to device-level global resets, the PSC provides the capability to cause local resets to
peripherals and/or the CPU.
6.5.1 Power-on Reset (POR Pin)
Power-on Reset (POR) is initiated by the POR pin and is used to reset the entire chip, including the
emulation logic. Power-on Reset is also referred to as a cold reset since the device usually goes through a
power-up cycle. During power-up, the POR pin must be asserted (driven low) until the power supplies
have reached their normal operating conditions. If an external 27-MHz oscillator is used on the MXI/CLKIN
pin, the source clock should also be running at the correct frequency prior to de-asserting the POR pin.
Note: A device power-up cycle is not required to initiate a Power-on Reset.
The following sequence must be followed during a Power-on Reset.
1. Wait for the power supplies to reach normal operating conditions while keeping the POR pin asserted
(driven low).
2. Wait for the input clock source to be stable while keeping the POR pin asserted (low).
3. Once the power supplies and the input clock source are stable, the POR pin must remain asserted
(low) for a minimum of 12 MXI cycles.
Within the low period of the POR pin, the following happens:
–
The reset signals flow to the entire chip (including the emulation logic), resetting the modules on
chip.
–
The PLL Controller clocks start at the frequency of the MXI clock. The clocks are propagated
throughout the chip to reset the chip synchronously. By default, both PLL1 and PLL2 are in reset
and unlocked. The PLL Controllers default to PLL Bypass Mode.
–
The RESETOUT pin stays asserted (low), indicating the device is in reset.
4. The POR pin may now be deasserted (driven high).
When the POR pin is deasserted (high), the configuration pin values are latched and the PLL
Controllers changed their system clocks to their default divide-down values. Both PLL Controllers are
still in PLL Bypass Mode. Other device initialization also begins.
5. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At the
end of these 10 cycles, the RESETOUT pin is deasserted (driven high).

The I/O pins are controlled by the default peripherals (default peripherals are determined by
PINMUX0 and PINMUX1 registers).
The clock and reset of each peripheral is determined by the default settings of the Power and Sleep
Controller (PSC).
–
–
The PLL Controllers are operating in PLL Bypass Mode.
The C64x+ begins executing from DSPBOOTADDR (determined by bootmode selection).
After the reset sequence, the boot sequence begins. For more details on the boot sequence, see the
Using the TMS320DM643x Bootloader Application Report (literature number SPRAAG0).
After the boot sequence, follow the software initialization sequence described in Section 3.8, Device
Initialization Sequence After Reset.
6.5.1.1 Usage of POR versus RESET Pins
POR and RESET are independent resets.
If the device needs to go through a power-up cycle, POR (not RESET) must be used to fully reset the
device.
In functional end-system, emulation/debugger logic is typically not needed; therefore, the recommendation
for functional end-system is to use the POR pin for full device reset. If RESET pin is not needed, it can be
pulled inactive (high) via an external pullup resistor.
In a debug system, it is typically desirable to allow the reset of the device without crashing an emulation
session. In this case, the user can use the POR pin to achieve full device reset and use the RESET pin to
achieve a debug reset—which resets the entire device except emulation logic.
6.5.1.2 Latching Boot and Configuration Pins
Internal to the chip, the two device reset pins RESET and POR are logically AND’d together only for the
purpose of latching device boot and configuration pins. The values on all device and boot configuration
pins are latched into the BOOTCFG register when the logical AND of RESET and POR transitions from
low-to-high.
6.5.2 Warm Reset (RESET Pin)
A Warm Reset is activated by driving the RESET pin active low. This resets everything in the device
except the emulation logic. An emulator session will stay alive during warm reset.
For more information on POR vs. RESET usage, see Section 6.5.1.1, Usage of POR versus RESET Pins
and Section 6.5.1.2, Latching Boot and Configuration Pins.
The following sequence must be followed during a Warm Reset:
1. Power supplies and input clock source should already be stable.
2. The RESET pin must be asserted (low) for a minimum of 12 MXI cycles.
Within the low period of the RESET pin, the following happens:
–
–
–
The reset signals flow to the entire chip resetting all the modules on chip, except the emulation
logic.
The PLL Controllers are reset thereby, switching back to PLL Bypass Mode and resetting all their
registers to default values. Both PLL1 and PLL2 are placed in reset and lose lock.
The RESETOUT pin becomes asserted (low), indicating the device is in reset.
3. The RESET pin may now be deasserted (driven high).
When the RESET pin is deasserted (high), the configuration pin values are latched and the PLL
Controllers changed their system clocks to their default divide-down values. Both PLL Controllers are
still in PLL Bypass Mode. Other device initialization also begins.
4. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At the
end of these 10 cycles, the RESETOUT pin is deasserted (driven high).

After the boot sequence, follow the software initialization sequence described in Section 3.8, Device
Initialization Sequence After Reset.
6.5.3 Maximum Reset
A Maximum (Max) Reset is initiated by the emulator or the watchdog timer (Timer 2). The effects are the
same as a warm reset, except the device boot and configuration pins are not re-latched. The emulator
initiates a maximum reset via the ICEPICK module. This ICEPICK initiated reset is non-maskable. When
the watchdog timer counter reaches zero, this will also initiate a maximum reset to recover from a runaway
condition. The watchdog timeout reset condition is masked if the TIMERCTL.WDRST bit is cleared to "0".
To invoke the maximum reset via the ICEPICK module, the user can perform the following from the Code
Composer Studio™ IDE menu: Debug→Advanced Resets→System Reset
This is the Max Reset sequence:
1. Max Reset is initiated by the emulator or the watchdog timer.
During this time, the following happens:
–
–
–
The reset signals flow to the entire chip resetting all the modules on chip except the emulation
logic.
The PLL Controllers are reset thereby, switching back to PLL Bypass Mode and resetting all their
registers to default values. Both PLL1 and PLL2 are placed in reset and lose lock.
The RESETOUT pin becomes asserted (low), indicating the device is in reset.
2. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At the
end of these 10 cycles, the RESETOUT pin is deasserted (driven high).

PINMUX0 and PINMUX1 registers).
–
The clock and reset of each peripheral is determined by the default settings of the Power and Sleep

–
–
The PLL Controllers are operating in PLL Bypass Mode.
The C64x+ begins executing from DSPBOOTADDR (determined by bootmode selection).
After the reset sequence, the boot sequence begins. Since the boot and configuration pins are not latched
with a Max Reset, the previous values (as shown in the BOOTCFG register) are used to select the boot
mode. For more details on the boot sequence, see the Using the TMS320DM643x Bootloader Application
Report (literature number SPRAAG0).
After the boot sequence, follow the software initialization sequence described in Section 3.8, Device
Initialization Sequence After Reset.

6.5.4 CPU Local Reset
The C64x+ DSP CPU has an internal reset input that allows a host (PCI/HPI) to control it. This reset is
configured through a register bit (MDCTL[39].LRST) in the Power Sleep Controller (PSC) module. When in
C64x+ local reset, the slave DMA port on C64x+ will remain active and the internal memory will be
accessible. For procedures on asserting and de-asserting CPU local reset by the host, see the
TMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978).
For information on peripheral selection at the rising edge of POR or RESET, see Section 3, Device
Configurations of this data manual.
6.5.5 Peripheral Local Reset
The user can configure the local reset and clock state of a peripheral through programming the PSC.
Table 6-4, DM6433 LPSC Assignments identifies the LPSC numbers and the peripherals capable of being
locally reset by the PSC. For more detailed information on the programming of these peripherals by the
PSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978).
6.5.6 Reset Priority
If any of the above reset sources occur simultaneously, the PLLC only processes the highest priority reset
request. The reset request priorities are as follows (high to low):
•
•
•
•
Power-on Reset
Maximum Reset
Warm Reset
CPU Reset
6.5.7 Reset Controller Register
The Reset Type Status (RSTYPE) register (01C4 00E4) is the only register for the reset controller. This
register falls in the same memory range as the PLL1 controller registers (see Table 6-18 for the PLL1
Controller Registers (including Reset Controller)). For more details on the RSTYPE register, see the
TMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978).
6.5.8 Pin Behaviors at Reset
During normal operations, pins are controlled by the respective peripheral selected in the PINMUX0 or
PINMUX1 register. During device level global reset, the pin behaves as follows:
Multiplexed Boot and Configuration Pins
These pins are forced 3-stated when RESETOUT is asserted (low). This is to ensure the proper boot and
configuration values can be latched on these multiplexed pins. This is particularly useful in the case where
the boot and configuration values are driven by an external control device. After RESETOUT is
deasserted (high), these pins are controlled by their respective default peripheral.
•
Boot and Configuration Pins Group: YOUT6/GP[28], YOUT5/GP[27], YOUT4/GP[26]/(FASTBOOT),
YOUT3/GP[25]/(BOOTMODE3), YOUT2/GP[24]/(BOOTMODE2), YOUT1/GP[23]/(BOOTMODE1),
YOUT0/GP[22]/(BOOTMODE0), R0/EM_A[4]/GP[10]/(AEAW2/PLLMS2),
G1/EM_A[1]/(ALE)/GP[9]/(AEAW1/PLLMS1), B1/EM_A[2]/(CLE)/GP[8]/(AEAW0/PLLMS0),

Default Power Down Pins
As discussed in Section 3.2, Power Considerations, the VDD3P3V_PWDN register controls power to the
3.3-V pins. The VDD3P3V_PWDN register defaults to powering down some 3.3-V pins to save power. For
more details on the VDD3P3V_PWDN register and which 3.3-V pins default to powerup or powerdown,
Section 3.2, Power Considerations. The pins that default to powerdown, are both reset to powerdown and
high-impedance. They remain in that state until configured otherwise by VDD3P3_PWDN and
PINMUX0/PINMUX1 programming.
•
Default Power Down Pin Group: GP[4]/PWM1, ACLKR0/CLKX0/GP[99], AFSR0/DR0/GP[100],
AHCLKR0/CLKR0/GP[101], AXR0[3]/FSR0/GP[102], AXR0[2]/FSX0/GP[103], AXR0[1]/DX0/GP[104],
AXR0/GP[105], ACLKX0/GP[106], AFSX0/GP[107], AHCLKX0/GP[108], AMUTEIN0/GP[109],
AMUTE0/GP[110], TOUT1L/GP[55], TINP1L/GP[56], CLKS0/TOUT0L/GP[97], TINP0L/GP[98],
URXD0/GP[85], UTXD0/GP[86], UCTS0/GP[87], and URTS0/PWM0/GP[88].
All Other Pins
During RESETOUT assertion (low), all other pins are controlled by the default peripheral. The default
peripheral is determined by the default settings of the PINMUX0 or PINMUX1 registers.
Some of the PINMUX0/PINMUX1 settings are determined by configuration pins latched at reset. To
determine the reset behavior of these pins, see Section 3.7, Multiplexed Pin Configurations and read the
rest of the this subsection to understand how that default peripheral controls the pin.
The reset behaviors for all these other pins are categorized as follows (also see Figure 6-7 and Figure 6-8
in Section 6.5.9, Reset Electrical Data/Timing):
•
•
•
Z+/Low Group (Z Longer-to-Low Group): These pins are 3-stated when device-level global reset
source (e.g., POR, RESET, or Max Reset) is asserted. These pins remain 3-stated throughout

6.6 External Clock Input From MXI/CLKIN Pin
The DM6433 device includes two options to provide an external clock input:
•
•
Use an on-chip oscillator with external crystal.
Use an external 1.8-V LVCMOS-compatible clock input.
The optimal external clock input frequency is 27 MHz. Section 6.6.1 provides more details on Option 1,
using an on-chip oscillator with external crystal. Section 6.6.2 provides details on Option 2, using an
external 1.8-V LVCMOS-compatible clock input.
6.6.1 Clock Input Option 1—Crystal
In this option, a crystal is used as the external clock input to the DM6433.
The 27-MHz oscillator provides the reference clock for all DM6433 subsystems and peripherals. The
on-chip oscillator requires an external 27-MHz crystal connected across the MXI and MXO pins, along
with two load capacitors, as shown in Figure 6-9. The external crystal load capacitors must be connected
only to the 27-MHz oscillator ground pin (MXVSS). Do not connect to board ground (VSS). The MXVDD pin
can be connected to the same 1.8 V power supply as DVDDR2
.

The load capacitors, C1 and C2, should be chosen such that the equation is satisfied (typical values are
C1 = C2 = 10 pF). CL in the equation is the load specified by the crystal manufacturer. All discrete
components used to implement the oscillator circuit should be placed as close as possible to the
associated oscillator pins (MXI and MXO) and to the MXVSS pin.

VPBE is used for NTSC or PAL compliant video output, TI recommends a 27-MHz, 50-ppm crystal. For more details on this NTSC and
PAL compliant output video, see Section 6.10.2, Video Processing Back-End (VPBE).

The external connections are shown in Figure 6-10. The MXI/CLKIN pin is connected to the 1.8-V
LVCMOS-Compatible clock source. The MXO pin is left unconnected. The MXVSS pin is connected to

6.7 Clock PLLs
There are two independently controlled PLLs on DM6433. PLL1 generates the frequencies required for the
DSP, DMA, and other peripherals. PLL2 generates the frequencies required for the DDR2 interface and
the VPBE in certain modes. The recommended reference clock for both PLLs is the 27-MHz crystal input.
6.7.1 PLL1 and PLL2
Both PLL1 and PLL2 power is supplied externally via the 1.8 V PLL power-supply pin (PLLPWR18). An
external EMI filter circuit must be added to PLLPWR18, as shown in Figure 6-11. The 1.8-V supply of the
EMI filter must be from the same 1.8-V power plane supplying the device’s 1.8-V I/O power-supply pins
(DVDDDR2). TI recommends EMI filter manufacturer Murata, part number NFM18CC222R1C3.
All PLL external components (C1, C2, and the EMI Filter) must be placed as close to the device as
possible. For the best performance, TI recommends that all the PLL external components be on a single
side of the board without jumpers, switches, or components other than the ones shown in Figure 6-11. For
reduced PLL jitter, maximize the spacing between switching signals and the PLL external components
(C1, C2, and the EMI Filter).

The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements,
see Section 6.7.4, Clock PLL Electrical Data/Timing (Input and Output Clocks).
There is an allowable range for PLL multiplier (PLLM). There is a minimum and maximum operating
frequency for MXI/CLKIN, PLLOUT, and the device clocks (SYSCLKs). The PLL Controllers must be
configured not to exceed any of these constraints documented in this section (certain combinations of
external clock inputs, internal dividers, and PLL multiply ratios might not be supported). For these
constraints (ranges), see Table 6-14 through Table 6-16.

PLL2_SYSCLK1 (to DDR2 PHY)
(1) MXI/CLKIN input clock is used for both PLL Controllers (PLLC1 and PLLC2).
Both PLL1 and PLL2 have stabilization, lock, and reset timing requirements that must be followed.
The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to
become stable after the PLL is powered up (after PLLCTL.PLLPWRDN bit goes through a 1-to-0
transition). The PLL should not be operated until this stabilization time has expired. This stabilization step
must be applied after these resets—a Power-on Reset, a Warm Reset, or a Max Reset, as the
PLLCTL.PLLPWRDN bit resets to a "1". For the PLL stabliziation time value, see Table 6-17.
The PLL reset time is the amount of wait time needed for the PLL to properly reset (writing PLLRST = 0)
before bringing the PLL out of reset (writing PLLRST = 1). For the PLL reset time value, see Table 6-17.
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1
with PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). For the
PLL lock time value, see Table 6-17.

6.7.3 Clock PLL Considerations with External Clock Sources
If the internal oscillator is bypassed, to minimize the clock jitter a single clean power supply should power
both the DM6433 device and the external clock oscillator circuit. The minimum CLKIN rise and fall times
should also be observed. For the input clock timing requirements, see Section 6.7.4, Clock PLL Electrical
Data/Timing (Input and Output Clocks).
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock
source must meet the device requirements in this data manual (see Section 5.3, Electrical Characteristics
Over Recommended Ranges of Supply Voltage and Operating Temperature and Section 6.7.4, Clock PLL

6.8 Interrupts
The C64x+ DSP interrupt controller combines device events into 12 prioritized interrupts. The source for
each of the 12 CPU interrupts is user programmable and is listed in Table 6-21. Also, the interrupt
controller controls the generation of the CPU exception and emulation interrupts. The NMI input to the
C64x+ DSP interrupt controller is not connected internally; therefore, the NMI interrupt is not available.
Table 6-22 summarizes the C64x+ interrupt controller registers and memory locations. For more details on
DSP interrupt controller, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literature
number SPRU978).

(2) Setup before end of STROBE phase (if no extended wait states are inserted) by which EM_WAIT must be asserted to add extended
wait states. Figure 6-16 and Figure 6-17 describe EMIF transactions that include extended wait states inserted during the STROBE
phase. However, cycles inserted as part of this extended wait period should not be counted; the 4E requirement is to the start of where
the HOLD phase would begin if there were no extended wait cycles.

6.9.4 DDR2 Memory Controller
The DDR2 Memory Controller is a dedicated interface to DDR2 SDRAM. It supports JESD79D-2A
standard compliant DDR2 SDRAM Devices and can interface to either 16-bit or 32-bit DDR2 SDRAM
devices. For details on the DDR2 Memory Controller, see the TMS320DM643x DMP DDR2 Memory
Controller User’s Guide (literature number SPRU986).
DDR2 SDRAM plays a key role in a DaVinci-based system. Such a system is expected to require a
significant amount of high-speed external memory for:
•
•
•
Numerous OSD display buffers
Buffering for intermediate data while performing video decode functions
Storage of executable code for the DSP
A memory map of the DDR2 Memory Controller registers is shown in Table 6-26.

6.10.2 Video Processing Back-End (VPBE)
The Video Processing Back-End (VPBE) consists of the On-Screen Display (OSD) module, the Video
Encoder (VENC) including the Digital LCD (DLCD) and Analog (i.e., DAC) interfaces. The video encoder
generates analog video output. The DLCD controller generates digital RGB/YCbCr data output and timing
signals.
The VPBE register memory mapping is shown in Table 6-31.

To ensure NTSC and PAL compliant output video, the stability of the input clock source is very important.
TI recommends a 27-MHz, 50-ppm crystal. Ceramic oscillators are not recommended. The NTSC/PAL
color sub-carrier frequency is derived from the 27-MHz clock; therefore, if the 27-MHz clock drifts, then the
color sub-carrier frequency will drift as well. Assuming no 27-MHz frequency drift, the color sub-carrier
frequency is generated as follows:

= 4.4332628318 MHz

To ensure the color sub-carrier frequency will not drift out of specification, the user must follow the crystal
requirements discussed in Section 6.6.1, Clock Input Option 1—Crystal. Alternatively, if the VPBE input
clock is sourced from the VPBECLK, this clock must have a frequency stability of ±50 ppm to ensure
NTSC and PAL compliant output video.
6.10.2.1 On-Screen Display (OSD)
The major function of the OSD module is to gather and blend video data and display/bitmap data before
feeding it to the Video Encoder (VENC) in YCbCr format. The video and display data is read from an
external memory, typically DDR2. The OSD is programmed via control and parameter registers. The
following are the primary features that are supported by the OSD.
•
Simultaneous display of two video windows and two OSD windows (VIDWIN0/VIDWIN1 and
OSDWIN0/OSDWIN1).
–
–
–
–
–
–
–
–
–
Separate enable for each window
Programmable width, height, and base starting coordinates for each window
External memory address and offset registers for each window
Support for x2 and x4 zoom in both the horizontal and vertical direction
OSDWIN1 can be used as an attribute window for OSDWIN0
Attribute window blinking intervals
Field/frame mode for the windows (interlaced/progressive)
Eight step blending process between the OSD and video windows
Transparency support for the OSD and video data (when a bitmap pixel is zero, there will be no
blending for that corresponding video pixel)
–
–
Resize from VGA to NTSC/PAL (640x480 to 720x576) for both the OSD and video windows
Reads in YCbCr data in 4:2:2 format from external memory, with the capability for swapping the
order of the CbCr component in the 32-bit word (this is relevant to the two video windows)
–
–
Support for a ping-pong buffer scheme that can be used for VIDWIN0 (allows for video data to be
accessed from two different locations in DDR2)
Each OSD window (either one, but not both at the same time) is capable of reading in RGB data

(16-bit data with six bits for the green and five bits each for the red and blue colors) instead of
bitmap data in YCbCr format restricted to a maximum of 8-bits
–
–
The OSD bitmap data width is selectable between 1, 2, 4, or 8-bits.
Each OSD window supports 16 entries for the bitmap (to index into a 256 entry RAM/ROM CLUT
table).
–
Indirect support for 24-bit RGB input data (which will be transformed into 16-bit YCbCr video
window data) via the wrapper interface in the VPBE.
•
•
Support for a rectangular cursor window and a programmable background color selection.
–
Programmable color palette with the ability to select between a RAM/ROM table with support for
256 colors.
–
–
The width, height, and color of the cursor is programmable.
The display priority is: Rectangular-Cursor > OSDWIN1 > OSDWIN0 > VIDWIN1 > VIDWIN0 >
background color
Support for attenuation of the YCbCr values for the REC601 standard.
The following restrictions exist in the OSD module.
•
•
•
Both the OSD windows and VIDWIN1 should be fully contained inside VIDWIN0.
When one of the OSD windows is set in RGB mode, it cannot overlap with VIDWIN1.
The OSD cannot support more than 256 color entries in the CLUT RAM/ROM. Some applications
require higher number of entries, and one workaround is to use VIDWIN1 as an overlay mimicking the
OSD window. Another option is to use the RGB mode for one of the OSD windows which allows for a
total of 16-bits for the R, G, and B colors (64K colors).
•
•
•
•
The OSD can only read YCbCr in 4:2:2 interleaved format for the video windows. Other formats, either
color separate storage or 4:4:4/4:2:0 interleaved data is not supported.
If the vertical resize filter is enabled for either of the video windows, the maximum horizontal window
dimension cannot be greater than 720 currently.
It is not possible to use both of the CLUT ROMs at the same time. However, one window can use
RAM while another uses ROM.
The 24-bit RGB input mode is only valid for one of the two video windows (programmable) and does
not apply to the OSD windows.
The OSD register memory mapping is shown in Table 6-32.

The DM6433's analog video DAC outputs are designed to drive a 500-Ω load. Figure 6-23 describes a
typical circuit that will permit connecting the analog video output from the DM6433 device to standard
75-Ω impedance video systems. Another solution is to use a Video Amplifier, such as the Texas
Instruments' OPA361, which provides a complete solution to the typical output circuit shown in
Figure 6-23.

(1) The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
(2) A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then be
met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns
(according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
(3) A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
(4) The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
(5) Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

6.13 Host-Port Interface (HPI) Peripheral
6.13.1 HPI Device-Specific Information
The DM6433 device includes a user-configurable 16-bit Host-port interface (HPI16).
Software handshaking via the HRDY bit of the Host Port Control Register (HPIC) is not supported on the
DM6433.
The DM6433 HPI does not support the HAS feature. For proper device operation, the HAS pin must be
pulled up via an external resistor.

(1) There are two 32-bit HPIA registers: HPIAR for read operations and HPIAW for write operations. The HPI can be configured such that
HPIAR and HPIAW act as a single 32-bit HPIA (single-HPIA mode) or as two separate 32-bit HPIAs (dual-HPIA mode) from the
perspective of the Host. The CPU can access HPIAW and HPIAR independently. For more details about the HPIA registers and their
modes, see the TMS320DM643x DMP Host Port Interface (HPI) User's Guide (literature number SPRU998).

6.14 Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
•
•
•
•
Full-duplex communication
Double-buffered data registers, which allow a continuous data stream
Independent framing and clocking for receive and transmit
Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
•
External shift clock or an internal, programmable frequency shift clock for data transfer
If internal clock source is used, the CLKGDV field of the Sample Rate Generator Register (SRGR) must
always be set to a value of 1 or greater.
For more detailed information on the McBSP peripheral, see the TMS320DM643x DMP Multichannel

(4) FSRP = FSXP = 1. As a SPI Master, FSX is inverted to provide active-low slave-enable output. As a Slave, the active-low signal input
on FSX and FSR is inverted before being used internally.
CLKXM = FSXM = 1, CLKRM = FSRM = 0 for Master McBSP
CLKXM = CLKRM = FSXM = FSRM = 0 for Slave McBSP
(5) FSX should be low before the rising edge of clock to enable Slave devices and then begin a SPI transfer at the rising edge of the Master
clock (CLKX).

6.15 Multichannel Audio Serial Port (McASP0) Peripheral
The McASP functions as a general-purpose audio serial port optimized for the needs of multichannel
audio applications. The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated
Sound (I2S) protocols, and intercomponent digital audio interface transmission (DIT).
6.15.1 McASP0 Device-Specific Information
The DM6433 device includes one multichannel audio serial port (McASP) interface peripheral (McASP0).
The McASP0 is a serial port optimized for the needs of multichannel audio applications.
The McASP0 consists of a transmit and receive section. These sections can operate completely
independently with different data formats, separate master clocks, bit clocks, and frame syncs or
alternatively, the transmit and receive sections may be synchronized. The McASP module also includes a
pool of 16 shift registers that may be configured to operate as either transmit data or receive data.
The transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM)
synchronous serial format or in a digital audio interface (DIT) format where the bit stream is encoded for
S/PDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP supports the TDM
synchronous serial format.
The McASP can support one transmit data format (either a TDM format or DIT format) and one receive
format at a time. All transmit shift registers use the same format and all receive shift registers use the
same format. However, the transmit and receive formats need not be the same.
Both the transmit and receive sections of the McASP also support burst mode which is useful for
non-audio data (for example, passing control information between two DSPs).
The McASP peripheral has additional capability for flexible clock generation, and error detection/handling,
as well as error management.
For more detailed information on and the functionality of the McASP0 peripheral, see the TMS320DM643x
DMP Multichannel Audio Serial Port (McASP) User's Guide (literature number SPRU980).

6.16 Ethernet Media Access Controller (EMAC)
The Ethernet Media Access Controller (EMAC) provides an efficient interface between DM6433 and the
network. The DM6433 EMAC supports both 10Base-T (10 Mbits/second [Mbps]) and 100Base-TX (100
Mbps) in either half- or full-duplex mode. The EMAC module also supports hardware flow control and
quality of service (QOS) support.
The EMAC controls the flow of packet data from the DM6433 device to the PHY. The MDIO module
controls PHY configuration and status monitoring.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the “Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) Access Method and Physical Layer” specifications. The IEEE
802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviation from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER.
Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will
intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame
will be detected as an error by the network.
Both the EMAC and the MDIO modules interface to the DM6433 device through a custom interface that
allows efficient data transmission and reception. This custom interface is referred to as the EMAC control
module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to
multiplex and control interrupts.
For the DM6433 Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO)
Module User's Guide (literature number SPRU941) which describes the DM6433 EMAC peripheral in
detail, see Section 2.9, Documentation Support section . For a list of supported registers and register
fields, see Table 6-65 [Ethernet MAC (EMAC) Control Registers] and Table 6-66 [EMAC Statistics
Registers] in this data manual.

6.17 Management Data Input/Output (MDIO)
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to
interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO
module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the
negotiation results, and configure required parameters in the EMAC module for correct operation. The
module is designed to allow almost transparent operation of the MDIO interface, with very little
maintenance from the core processor. Only one PHY may be connected at any given time.
For more detailed information on the MDIO peripheral, see the Documentation Support section for the
Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module Reference
Guide. For a list of supported registers and register fields, see Table 6-73 [MDIO Registers] in this data
manual.

6.19 Peripheral Component Interconnect (PCI)
The DM6433 DMP supports connections to PCI-compliant devices via the integrated PCI master/slave bus
interface. The PCI port interfaces to DSP internal resources via the data switched central resource. The
data switched central resource is described in more detail in Section 4, System Interconnect.
For more detailed information on the PCI port peripheral module, see the TMS320DM643x DMP
Peripheral Component Interconnect (PCI) User's Guide (literature number SPRU985).
6.19.1 PCI Device-Specific Information
The PCI peripheral can act both as a PCI bus master and as a target. It supports PCI bus operation of
speeds up to 33 MHz and uses a 32-bit data/address bus.
On the DM6433 device, the pins of the PCI peripheral are multiplexed with the pins of the VPSS, EMIFA,
GPIO, HPI, VLYNQ, and EMAC peripherals. For more detailed information on how to select PCI, see
Section 3, Device Configurations.
The DM6433 device provides an initialization mechanism through which the default values for some of the
PCI configuration registers can be read from an I2C EEPROM. Table 6-81 shows the registers which can
be initialized through the PCI auto-initialization. The default value of these registers when PCI
auto-initialization is not used is also shown in Table 6-81. PCI auto-initialization is enabled by selecting
PCI boot with auto-initialization. For information on how to select PCI boot with auto-initialization, see
Section 3.4.1, Boot Modes. For more information on PCI auto-initialization, see the TMS320DM643x DMP
Peripheral Component Interconnect (PCI) User's Guide (literature number SPRU985) and the Using the
TMS320DM643x Bootloader Application Report (literature number SPRAAG0).
The PCI peripheral is a master peripheral within the DM6433 DMP.

6.22 General-Purpose Input/Output (GPIO)
The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.
When configured as an output, a write to an internal register can control the state driven on the output pin.
When configured as an input, the state of the input is detectable by reading the state of an internal
register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different
interrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.
The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GP[0:15]).
The DM6433 GPIO peripheral supports the following:
•
•
Up to 111 3.3-V GPIO pins, GP[0:110]
Interrupts:
–
–
–
Up to 8 unique GP[0:7] interrupts from Bank 0
7 GPIO bank (aggregated) interrupt signals from each of the 7 banks of GPIOs
Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIO
signal
•
•
DMA events:
–
–
Up to 8 unique GPIO DMA events from Bank 0
7 GPIO bank (aggregated) DMA event signals from each of the 7 banks of GPIOs
Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO
signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section
protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to
anther process during GPIO programming).
•
•
Separate Input/Output registers
Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals can
be toggled by direct write to the output register(s).
•
Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status and open-drain I/O cell, allows wired logic be implemented.
The memory map for the GPIO registers is shown in Table 6-95. For more detailed information on GPIOs,
see the TMS320DM643x DMP General-Purpose Input/Output (GPIO) User's Guide (literature number
SPRU988).

the GP[x] input changes through software polling of the GPIO register, the GP[x] input duration must be extended to allow DM6433
enough time to access the GPIO register through the internal bus.

6.23 IEEE 1149.1 JTAG
The JTAG(3) interface is used for BSDL testing and emulation of the DM6433 device.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or
exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by
TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted.
For maximum reliability, DM6433 includes an internal pulldown (IPD) on the TRST pin to ensure that
TRST will always be asserted upon power up and the device's internal emulation logic will always be
properly initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG
controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the device after powerup and externally
drive TRST high before attempting any emulation or boundary scan operations.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
