description
The TMS320VC5410 fixed-point, digital signal processor (DSP) (hereafter referred to as the ’5410 unless
otherwise specified) is based on an advanced modified Harvard architecture that has one program memory bus
and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a high degree of
parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis
of the operational flexibility and speed of this DSP is a highly specialized instruction set.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

description (continued)
Separate program and data spaces allow simultaneous access to program instructions and data, providing a
high degree of parallelism. Two read operations and one write operation can be performed in a single cycle.
Instructions with parallel store and application-specific instructions can fully utilize this architecture. In addition,
data can be transferred between data and program spaces. Such parallelism supports a powerful set of
arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle. The ’5410
also includes the control mechanisms to manage interrupts, repeated operations, and function calls.
NOTE:This data sheet is designed to be used in conjunction with the TMS320C5000 DSP Family Functional Overview
(literature number SPRU307).

O/Z
Parallel address bus A22 [most significant bit (MSB)] through A0 [least significant bit (LSB)]. The sixteen LSB
lines, A0 to A15, are multiplexed to address external memory (program, data) or I/O. The seven MSB lines, A16
to A22, address external program space memory. A22–A0 is placed in the high-impedance state in the hold
mode. A22–A0 also goes into the high-impedance state when OFF is low.
The address bus has a bus holder feature that eliminates passive components and the power dissipation
associated with them. The bus holder keeps the address bus at the previous logic level when the bus goes into
a high-impedance state.

outputting data or when RS or HOLD is asserted. D15–D0 also goes into the high-impedance state when OFF
is low.
The data bus has a bus holder feature that eliminates passive components and the power dissipation associated
with them. The bus holder keeps the data bus at the previous logic level when the bus goes into a

TERMINAL
NAME

I/O
DESCRIPTION
INITIALIZATION, INTERRUPT AND RESET OPERATIONS
Interrupt acknowledge signal. IACK indicates receipt of an interrupt and that the program counter is fetching the
interrupt vector location designated by A15–A0. IACK also goes into the high-impedance state when OFF is low.
IACK
O/Z
I
INT0
INT1
INT2
INT3
External user interrupt inputs. INT0–INT3 is prioritized and is maskable by the interrupt mask register (IMR) and
interrupt mode bit. INT0 –INT3 can be polled and reset by way of the interrupt flag register (IFR).
Nonmaskable interrupt. NMI is an external interrupt that cannot be masked by way of the INTM or the IMR. When
NMI is activated, the processor traps to the appropriate vector location.
NMI
I
I
Reset. RS causes the digitial signal processor (DSP) to terminate execution and forces the program counter to
0FF80h. When RS is brought to a high level, execution begins at location 0FF80h of program memory. RS affects
various registers and status bits.
RS
Microprocessor/microcomputer mode select pin. If active low at reset (microcomputer mode), MP/MC causes
the internal program ROM to be mapped into the upper 16K words of program memory space. In the
microprocessor mode, off-chip memory and its corresponding addresses (instead of internal program ROM) are
accessed by the DSP.
MP/MC
I
MULTIPROCESSING SIGNALS
Branch control. A branch can be conditionally executed when BIO is active. If low, the processor executes the
conditional instruction. The BIO condition is sampled during the decode phase of the pipeline for the XC
instruction, and all other instructions sample BIO during the read phase of the pipeline.
BIO
XF
I
External flag output (latched software-programmable signal). XF is set high by the SSBX XF instruction, set low
by RSBX XF instruction or by loading ST1. XF is used for signaling other processors in multiprocessor
configurations or used as a general-purpose output pin. XF goes into the high-impedance state when OFF is
low, and is set high at reset.
O/Z
MEMORY CONTROL SIGNALS
Data, program, and I/O space select signals. DS, PS, and IS are always high unless driven low for
communicating to a particular external space. Active period corresponds to valid address information. DS, PS,
and IS are placed into the high-impedance state in the hold mode; these signals also go into the high-impedance
state when OFF is low.
DS
PS
IS
O/Z
O/Z
I
Memory strobe signal. MSTRB is always high unless low-level asserted to indicate an external bus access to
data or program memory. MSTRB is placed in the high-impedance state in the hold mode; it also goes into the
high-impedance state when OFF is low.
MSTRB
READY
R/W
Data ready. READY indicates that an external device is prepared for a bus transaction to be completed. If the
device is not ready (READY is low), the processor waits one cycle and checks READY again. Note that the
processor performs ready detection if at least two software wait states are programmed. The READY signal is
not sampled until the completion of the software wait states.
Read/write signal. R/W indicates transfer direction during communication to an external device. R/W is normally
in the read mode (high), unless it is asserted low when the DSP performs a write operation. R/W is placed in
the high-impedance state in the hold mode; and it also goes into the high-impedance state when OFF is low.
O/Z

architecture
The ’VC5410 DSP implements the standard ’C54x CPU which uses an advanced, modified Harvard
architecture that maximizes processing power by maintaining three separate bus structures for data memory
and one for program memory. Separate program and data spaces allow simultaneous access to program
instructions and data, providing a high degree of parallelism. For example, two read operations and one write
operation can be performed in a single cycle. Instructions with parallel store and application-specific instructions
fully utilize this architecture. In addition, data can be transferred between data and program spaces. Such
parallelism supports a powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed
in a single machine cycle. In addition, the ’VC5410 includes the control mechanisms to manage interrupts,
repeated operations, and function calls.
For detailed information on the architecture of the C5000 family of DSPs, refer to the TMS320C5000 DSP
Family Functional Overview (literature number SPRU307).
memory
The ’VC5410 device provides both on-chip ROM and RAM memories to aid in system performance and
integration.
on-chip ROM with bootloader
The ’VC5410 features a 16K-word × 16-bit on-chip maskable ROM that can only be mapped into program
memory space.
Customers can arrange to have the ROM of the ’VC5410 programmed with contents unique to any particular
application.
A bootloader is available in the standard ’VC5410 on-chip ROM. This bootloader can be used to automatically
transfer user code from an external source to anywhere in the program memory at power up. If MP/MC of the
device is sampled low during a hardware reset, execution begins at location FF80h of the on-chip ROM. This
location contains a branch instruction to the start of the bootloader program. The standard ’VC5410 devices
provide different ways to download the code to accomodate various system requirements:

In the ’VC5410 ROM, 128 words are reserved for factory device-testing purposes. Application
code to be implemented in on-chip ROM must reserve these 128 words at addresses
FF00h–FF7Fh in program space.
on-chip RAM
The ’VC5410 device contains 8K words × 16-bit on-chip dual-access RAM (DARAM) and 56K words × 16-bit
of on-chip single-access RAM (SARAM).
The DARAM is composed of four blocks of 2K words each. Each block in the DARAM can support two reads
in one cycle, or a read and a write in one cycle. The DARAM is located in the address range 0080h–1FFFh in
data space, and can be mapped into program/data space by setting the OVLY bit to one.
The SARAM is composed of seven blocks of 8K words each. Each of these seven blocks is a single-access
memory. For example, an instruction word can be fetched from one SARAM block in the same cycle as a data
word is written to another SARAM block. The SARAM located in the address range 2000h–7FFFh in data space
can be mapped into program space by setting the OVLY bit to one, while the SARAM located in the address
range 18000h–1FFFFh in program space can be mapped into data space by setting the DROM bit to one.
on-chip memory security
The ’VC5410 device has a maskable option to protect the contents of on-chip memories. When the ROM protect
bit is set, no externally originating instruction can access the on-chip memory spaces. In addition, when the
ROM protect option is enabled, HPI8 read access is limited to address range 0001000h – 0001FFFh. Data
located outside this range cannot be read through the HPI8. Write access to the entire HPI8 memory map is
still maintained.

relocatable interrupt vector table
The reset, interrupt, and trap vectors are addressed in program space. These vectors are soft — meaning that
the processor, when taking the trap, loads the program counter (PC) with the trap address and executes the
code at the vector location. Four words, either two 1-word instructions or one 2-word instruction, are reserved
at each vector location to accommodate a delayed branch instruction which allows branching to the appropriate
interrupt service routine without the overhead.
At device reset, the reset, interrupt, and trap vectors are mapped to address FF80h in program space. However,
these vectors can be remapped to the beginning of any 128-word page in program space after device reset.
This is done by loading the interrupt vector pointer (IPTR) bits in the PMST register with the appropriate
128-word page boundary address. After loading IPTR, any user interrupt or trap vector is mapped to the new
128-word page.
NOTE: The hardware reset (RS) vector cannot be remapped because the hardware reset loads the IPTR
with 1s. Therefore, the reset vector is always fetched at location FF80h in program space.
extended program memory
The ’VC5410 uses a paged extended memory scheme in program space to allow access of up to 8192K of
program memory. In order to implement this scheme, the ’VC5410 includes several features which are also

Figure 3. Extended Program Memory
(On-Chip RAM Mapped in Program Space and Data Space, OVLY = 1)
If the on-chip ROM is enabled (MP/MC = 0), it is enabled only on page 0. It is not mapped to any other page
in program memory.
The value of the XPC register defines the page selection. This register is memory-mapped into data space to
address 001Eh. At a hardware reset, the XPC is initialized to 0.
To facilitate page-switching through software, the ’VC5410 has six special instructions that affect the XPC:
D

FB[D] pmad (23 bits) – Far branch
FBACC[D] Accu[22:0] – Far branch to the location specified by the value in accumulator A or

data memory
The data memory space addresses up to 64K of 16-bit words. The device automatically accesses the on-chip
RAM when addressing within its bounds. When an address is generated outside the RAM bounds, the device
automatically generates an external access.
The advantages of operating from on-chip memory are as follows:
D

D

Software-programmable wait-state generator
Programmable bank-switching
A host-port interface (HPI8)
Three multichannel buffered serial ports (McBSPs)
A hardware timer
A clock generator with a multiple phase-locked loop (PLL)
Enhanced external parallel interface (XIO2)
A DMA controller (DMA)
software-programmable wait-state generator
The software-programmable wait-state generator can extend external bus cycles by up to fourteen CLKOUT
cycles, providing a convenient means of interfacing the ’VC5410 with slower external devices. Devices that
require more than fourteen wait states can be interfaced using the hardware READY line. When all external
accesses are configured for zero wait states, the internal clocks to the wait-state generator are shut off; shutting
off these paths from the internal clocks allows the device to run with lower power consumption.
The software-programmable wait-state generator is controlled by the 16-bit software wait-state register
(SWWSR), which is memory-mapped to address 0028h in data space.
The program and data spaces each consist of two 32K-word blocks; the I/O space consists of one 64K-word block.
Each of these blocks has a corresponding 3-bit field in the SWWSR. These fields are shown in Figure 4 and
described in Table 2.
The value of a 3-bit field in SWWSR, in conjunction with the software wait-state multiplier (SWSM) bit in the
software wait-state control register (SWCR), specifies the number of wait states to be inserted for each access
in the corresponding space and address range.
D
D
When SWSM = 0, the possible values for the number of wait states are 0, 1, 2, 3, 4, 5, 6, and 7. This is the
default configuration.
When SWSM = 1, the possible values for the number of wait states are 0, 2, 4, 6, 8, 10, 12, and 14.
At reset, the SWWSR is set to 7FFFh, and SWSM to 0, configuring seven wait states for all external accesses.

programmable bank-switching
Programmable bank-switching logic allows the ’VC5410 to switch between external memory banks without
requiring external wait states for memories that need additional time to turn off. The bank-switching logic
automatically inserts one cycle when accesses cross a 32K-word memory-bank boundary inside program or
data space.
Bank-switching is defined by the bank-switching control register (BSCR), which is memory-mapped at
address 0029h. The bit fields of the BSCR are shown in Figure 6 and are described in Table 4.

programmable bank-switching (continued)
The ’VC5410 has an internal register that holds the MSB of the last address used for a read or write operation
in program or data space. In the non-consecutive bank switches (CONSEC = 0), if the MSB of the address used
for the current read does not match that contained in this internal register, the MSTRB (memory strobe) signal
is not asserted for one CLKOUT cycle. During this extra cycle, the address bus switches to the new address.
The contents of the internal register are replaced with the MSB for the read of the current address. If the MSB
of the address used for the current read matches the bits in the register, a normal read cycle occurs.
In non-consecutive bank switches (CONSEC = 0), if repeated reads are performed from the same memory
bank, no extra cycles are inserted. When a read is performed from a different memory bank, memory conflicts
are avoided by inserting an extra cycle. For more information, see the “enhanced external parallel interface
(XIO2)” section of this document.
The bank-switching mechanism automatically inserts one extra cycle in the following cases:
D

D

A memory read followed by another memory read from a different memory bank.
A program-memory read followed by a data-memory read.
A data-memory read followed by a program-memory read.
A program-memory read followed by another program-memory read from a different page.
parallel I/O ports
Each device has a total of 64K I/O ports. These ports can be addressed by the PORTR instruction or the PORTW
instruction. The IS signal indicates a read/write operation through an I/O port. The ’VC5410 can interface easily
with external devices through the I/O ports while requiring minimal off-chip address-decoding circuits.
enhanced host-port interface (HPI8)
The enhanced host-port interface (HPI8) in the ’VC5410 is an 8-bit parallel port used to interface a host
processor to the DSP. Data can be exchanged between the host processor and the DSP throughout the entire
on-chip memory via the DMA controller. The extended program memory pages are also accessible by both the
host and the DSP. The DSP and the host control the HPI8 activity through the HPI8 control register (HPIC). The
host can address memory through the HPI8 address register (HPIA).
Data transfers of 16-bit words occur as two consecutive bytes with a dedicated pin (HBIL) indicating whether
the high or low byte is being transmitted. Two pins (controlled by the host), HCNTL0 and HCNTL1, indicate
whether the being exchanged is the most significant or least significant byte. Control pins (HCNTL0 and
HCNTL1) determine whether the data is directed to the HPIA, the HPIC, or to memory. The DSP can interrupt
the host with a dedicated HINT pin that the host can acknowledge and clear.
The ’VC5410 is the first device in the C5000 family in which the HPI8 can address all on-chip memory, including
extended memory pages. Extended memory addresses are defined by a 23-bit address. The HPI8 sets the
upper 6 bits of the extended memory address by writing a one to the XHPIA bit in HPIC, and then writing address
bits A[22:16] into HPIA. The lower 16 bits of the extended memory address are set by writing a zero to XHPIA,
followed by writing bits A[15:0] to HPIA. Similar to previous implementations of the HPI, after a write is performed
to XHPIA or HPIA, a memory prefetch is initiated. The XHPIA bit is accessible only to the host. XHPIA is
uninitialized following reset. The host should always initialize XHPIA prior to the first HPI8 access following a
device reset.
The HPI8 interface has two data strobes (HDS1 and HDS2), a read/write strobe (HR/W), and an address strobe
(HAS), to enable a glueless interface to a variety of industry-standard host devices. The HPI8 is easily interfaced
to hosts with multiplexed address/data bus, separate address and data buses, one data strobe, and a read/write
strobe, or two separate strobes for read and write.

enhanced host-port interface (HPI8) (continued)
All memory accesses on the ’VC5410 are in shared-access mode, meaning both the DSP and the host can
access memory. Asynchronous host accesses are resynchronized internally, and in the event that the CPU and
the host both request access to the same memory block, the host has access priority. The HRDY pin provides
handshaking to the host during memory access.
The HPI8 also provides the capability to access memory during reset and power-down states. During reset, data
or application code can be loaded via the HPI8, and the application can be initiated through the HPI option of
the bootloader. During IDLE2/3 states, the HPI8 and the other six DMA channels continue to operate, and all
pending DMA events complete before the DSP stops the clocks. The HPI8 has higher priority than the other
six DMA channels. The HPI8 continues to have access to memory in IDLE2/3 even after the DSP has stopped
the internal clocks as long as X2/CLKIN is maintained. The ’VC5410 HPI8 also remains active during emulation
stop. The HPI8 can access any on-chip RAM on the device. The HPI8 memory map for the ’VC5410 is shown
in Figure 7. The HPI8 determines memory location by address only (program or data space is not relevant).

multichannel buffered serial ports
The ’VC5410 device provides three high-speed, full-duplex, multichannel buffered serial ports that allow direct
interface to other ’C54x/’LC54x devices, codecs, and other devices in a system. The McBSPs are based on the
standard serial-port interface found on other ’54x devices. Like their predecessors, the McBSPs provide:

The McBSPs consist of separate transmit and receive channels that operate independently. The external

External clock reference for the programmable clock generator
The first six pins listed are identical to the previous serial-port interface pins on the C5000 family of DSPs. The
BCLKS pin is an additional signal to provide a clock reference to the McBSP programmable clock generator.
As a compatibility option, the ’VC5410 is provided in a 144-pin TQFP package (designated PGE) that is
pin-compatible with the ’C548/549 devices. BCLKS is not implemented on this package.
On the transmitter, transmit frame synchronization and clocking are indicated by the BFSX and BCLKX pins,
respectively. The CPU or DMA can initiate transmission of data by writing to the data transmit register (DXR).
Data written to DXR is shifted out on the BDX pin through a transmit shift register (XSR). This structure allows
DXR to be loaded with the next word to be sent while the transmission of the current word is in progress.
On the receiver, receive frame synchronization and clocking are indicated by the BFSR and BCLKR pins
respectively. The CPU or DMA can read received data from the data receive register (DRR). Data received on
the BDR pin is shifted into a receive shift register (RSR) and then buffered in the receive buffer register (RBR).
If DRR is empty, the RBR contents are copied into DRR. If not, RBR holds the data until DRR is available. This
structure allows storage of the two previous words while the reception of the current word is in progress.

multichannel buffered serial ports (continued)
The CPU and DMA can move data to and from the McBSPs and can synchronize transfers based on McBSP
interrupts, event signals, and status flags. The DMA is capable of handling data movement between the
McBSPs and memory with no intervention from the CPU.
In addition to the standard serial-port functions, the McBSP provides programmable clock and frame
synchronization generation. Among the programmable functions are:
D
D
D
D
D
D
Frame synchronization pulse width
Frame period
Frame synchronization delay
Clock reference (internal vs. external)
Clock division
Clock and frame synchronization polarity
The on-chip companding hardware allows compression and expansion of data in either µ-law or A-law format.
When companding is used, transmit data is encoded according to specified companding law and received data
is decoded to 2s complement format.
The McBSP allows the multiple channels to be independently selected for the transmitter and receiver. When
the multiple channels are selected, each frame represents a time-division multiplexed (TDM) data stream. In
using TDM data streams, the CPU may only need to process a few of them. Thus, to save memory and bus
bandwidth, multichannel selection allows independent enabling of particular channels for transmission and
reception. Up to 32 channels in a bit stream of up to 128 channels can be enabled.
The clock-stop mode (CLKSTP) in the McBSP provides compatibility with the serial peripheral interface (SPI)
protocol. Clock-stop mode works with only single-phase frames and one word per frame. The word sizes
supported by the McBSP are programmable for 8-, 12-, 16-, 20-, 24-, or 32-bit operation. When the McBSP is
configured to operate in SPI mode, both the transmitter and the receiver operate together as a master or as a
slave.
The McBSP is fully static and operates at arbitrarily low clock frequencies. The maximum frequency is CPU
clock frequency divided by 2.
hardware timer
The ’VC5410 device features a 16-bit timing circuit with a 4-bit prescaler. The timer counter is decremented by
one every CPU clock cycle. Each time the counter decrements to 0, a timer interrupt is generated. The timer
can be stopped, restarted, reset, or disabled by specific status bits.
clock generator
The clock generator provides clocks to the ’VC5410 device, and consists of an internal oscillator and a
phase-locked loop (PLL) circuit. The clock generator requires a reference clock input, which can be provided
by using a crystal resonator with the internal oscillator, or from an external clock source. The reference clock
input is then divided by two (DIV mode) to generate clocks for the ’VC5410 device, or the PLL circuit can be
used (PLL mode) to generate the device clock by multiplying the reference clock frequency by a scale factor,
allowing use of a clock source with a lower frequency than that of the CPU.The PLL is an adaptive circuit that,
once synchronized, locks onto and tracks an input clock signal.
When the PLL is initially started, it enters a transitional mode during which the PLL acquires lock with the input
signal. Once the PLL is locked, it continues to track and maintain synchronization with the input signal. Then,
other internal clock circuitry allows the synthesis of new clock frequencies for use as master clock for the
’VC5410 device.

This clock generator allows system designers to select the clock source. The sources that drive the clock
generator are:
D
D
A crystal resonator circuit. The crystal resonator circuit is connected across the X1 and X2/CLKIN pins of
the ’VC5410 to enable the internal oscillator.
An external clock. The external clock source is directly connected to the X2/CLKIN pin, and X1 is left
unconnected.
The software-programmable PLL features a high level of flexibility, and includes a clock scaler that provides
various clock multiplier ratios, capability to directly enable and disable the PLL, and a PLL lock timer that can
be used to delay switching to PLL clocking mode of the device until lock is achieved.Devices that have a built-in
software-programmable PLL can be configured in one of two clock modes:
D
PLL mode. The input clock (X2/CLKIN) is multiplied by 1 of 31 possible ratios.
DIV (divider) mode. The input clock is divided by 2 or 4. Note that when DIV mode is used, the PLL can be
completely disabled in order to minimize power dissipation.
D
The software-programmable PLL is controlled using the 16-bit memory-mapped (address 0058h) clock mode
register (CLKMD). The CLKMD register is used to define the clock configuration of the PLL clock module. Note
that upon reset, the CLKMD register is initialized with a predetermined value dependent only upon the state of
the CLKMD1 – CLKMD3 pins. The CLKMD pin configured clock options are shown in Table 5.

enhanced external parallel interface (XIO2)
The ’VC5410 external interface has been redesigned to include several improvements, including: simplification
of the bus sequence, more immunity to bus contention when transitioning between read and write operation,
the ability for external memory access to the DMA controller, and optimization of the power-down modes.
The bus sequence on the ’VC5410 still maintains all of the same interface signals as on previous ’54x devices,
but the signal sequence has been simplified. Most external accesses now require 3 cycles composed of a
leading cycle, an active (read or write) cycle, and a trailing cycle. The leading and trailing cycles provide
additional immunity against bus contention when switching between read operations and write operations. To
maintain high-speed read access, a consecutive read mode that performs single-cycle reads as on previous
’54x devices is available.

The enhanced interface also provides the ability for DMA transfers to extend to external memory. For more
information on DMA capability, see the DMA sections that follow.
The enhanced interface improves the low-power performance already present on the ’C5000 family by
switching off the internal clocks to the interface when it is not being used. This power-saving feature is automatic,
requires no software setup, and causes no latency in the operation of the interface.
Additional features integrated in the enhanced interface are the ability to automatically insert bank-switching
cycles when crossing 32K memory boundaries (see the “programmable bank-switching” section), the ability to
program up to 14 wait states through software (see the “software-programmable wait-state generator” section),
and the ability to divide down CLKOUT by a factor of 1, 2, 3, or 4. Dividing down CLKOUT provides an alternative
to wait states when interfacing to slower external memory or peripheral devices. While inserting wait states
extends the bus sequence during read or write accesses, it does not slow down the bus signal sequences at
the beginning and the end of the access. Dividing down CLKOUT provides a method of slowing the entire bus
sequence when necessary. The CLKOUT divide-down factor is controlled through the DIVFCT field in the
bank-switching control register (BSCR).

intervention by the CPU. The DMA allows movements of data to and from internal program/data memory,
internal peripherals (such as the McBSPs), or external memory devices to occur in the background of CPU
operation. The DMA has six independent programmable channels, allowing six different contexts for DMA
operation.

The DMA has six channels. The DMA can keep track of the contexts of six independent block transfers.
The DMA has higher priority than the CPU for both internal and external accesses.
Each channel has independently programmable priorities.
Each channel’s source and destination address registers can have configurable indexes through memory
on each read and write transfer, respectively. The address may remain constant, be post-incremented, be
post-decremented, or be adjusted by a programmable value.

DMA priority level
Each DMA channel can be independently assigned high- or low-priority relative to each other. Multiple DMA
channels that are assigned to the same priority level are handled in a round-robin manner.

DMA source/destination address modification
The DMA provides flexible address-indexing modes for easy implementation of data management schemes
such as autobuffering and circular buffers. Source and destination addresses can be indexed separately and
can be post-incremented, post-decremented, or post-incremented with a specified index offset.
DMA in autoinitialization mode
The DMA can automatically reinitialize itself after completion of a block transfer. Some of the DMA registers can
be preloaded for the next block transfer through the DMA global reload registers (DMGSA, DMGDA, and
DMGCR). Autoinitialization allows:
D
D
Continuous operation: Normally, the CPU would have to reinitialize the DMA immediately after the
completion of the current block transfers, but with the global reload registers, it can reinitialize these values
for the next block transfer any time after the current block transfer begins.
Repetitive operation: The CPU does not preload the global reload register with new values for each block
transfer but only loads them on the first block transfer.
DMA transfer counting
The DMA channel element count register (DMCTRx) and the frame count register (DMFRCx) contain bit fields
that represent the number of frames and the number of elements per frame to be transferred.
D
Frame count. This 8-bit value defines the total number of frames in the block transfer. The maximum
number of frames per block transfer is 128 (FRAME COUNT= 0ffh). The counter is decremented upon the
last read transfer in a frame transfer. Once the last frame is transferred, the selected 8-bit counter is
reloaded with the DMA global frame reload register (DMGFR) if the AUTOINIT bit is set to 1. A frame count
of 0 (default value) means the block transfer contains a single frame.
D
Element count. This 16-bit value defines the number of elements per frame. This counter is decremented
after the read transfer of each element. The maximum number of elements per frame is 65536
(DMCTRn = 0ffffh). In autoinitialization mode, once the last frame is transferred, the counter is reloaded with
the DMA global count reload register (DMGCR).
DMA transfer in double-word mode
Double-word mode allows the DMA to transfer 32-bit words in any index mode. In double-word mode, two
consecutive 16-bit transfers are initiated and the source and destination addresses are automatically updated
following each transfer. In this mode, each 32-bit word is considered to be one element.
DMA channel index registers
The particular DMA channel index register is selected by way of the SIND and DIND fields in the DMA mode
control register (DMMCRx). Unlike basic address adjustment, in conjunction with the frame index DMFRI0 and
DMFRI1, the DMA allows different adjustment amounts depending on whether or not the element transfer is
the last in the current frame. The normal adjustment value (element index) is contained in the element index
registers DMIDX0 and DMIDX1. The adjustment value (frame index) for the end of the frame, is determined by
the selected DMA frame index register, either DMFRI0 or DMFRI1.
The element index and the frame index affect address adjustment as follows:
D
D
Element index: For all except the last transfer in the frame, the element index determines the amount to be
added to the DMA channel for the source/destination address register (DMSRCx/DMDSTx) as selected by
the SIND/DIND bits.
Frame index: If the transfer is the last in a frame, frame index is used for address adjustment as selected
by the SIND/DIND bits. This occurs in both single-frame and multi-frame transfers.

DMA interrupts
The ability of the DMA to interrupt the CPU based on the status of the data transfer is configurable and is
determined by the IMOD and DINM bits in the DMA channel mode control register (DMMCRn). The available
modes are shown in Table 6.

§
Texas Instrument DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be
designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage.
Excessive exposure to these conditions can adversely affect the long term reliability of the devices. System-level concerns such as bus contention
may require supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as or prior to the I/O
buffers and then powered down after the I/O buffers.
Refer to Figure 13 for 3.3-V device test load circuit values.

internal divide-by-two clock option with external crystal
The internal oscillator on the ’5410 is enabled by setting the CLKMD(1,2,3) pins to (1,0,0) at reset and
connecting a crystal or ceramic resonator across X1 and X2/CLKIN. The CPU clock frequency is one-half the
crystal’s oscillation frequency following reset. Since the internal oscillator can be used as a clock source to the
PLL, the crystal oscillation frequency can be multiplied to generate the CPU clock if desired.
The crystal should be in fundamental mode operation and parallel resonant with an effective series resistance
of 30 ohms and power dissipation of 1 mW. The connection of the required circuit, consisting of the crystal and
two load capacitors, is shown in Figure 14. The load capacitors, C and C , should be chosen such that the
1

equation below is satisfied. C in the equation is the load specified for the crystal.

†
The external interrupts (INT0–INT3, NMI) are synchronized to the core CPU by way of a two-flip-flop synchronizer that samples these inputs
with consecutive falling edges of CLKOUT. The input to the interrupt pins is required to represent a 1–0–0 sequence at the timing that is
corresponding to three CLKOUTs sampling sequence.
If the PLL mode is selected, then at power-on sequence, or at wakeup from IDLE3, RS must be held low for at least 50 µs to ensure
synchronization and lock-in of the PLL.
‡
§
¶
Note that RS may cause a change in clock frequency, therefore changing the value of H.
The diagram assumes clock mode is divide-by-2 and the CLKOUT divide factor is set to no-divide mode (DIVFCT=00 field in the BSCR).

C = BCLKX low pulse width = T/2 when CLKGDV is odd or zero and = (CLKGDV/2) * 2H when CLKGDV is even
FSRP = FSXP = 1. As a SPI master, BFSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on BFSX
and BFSR is inverted before being used internally.
§
CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP
CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP
BFSX 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
(BCLKX).

For all SPI slave modes, CLKG is programmed as 1/2 of the CPU clock by setting CLKSM = CLKGDV = 1.
T = BCLKX period = (1 + CLKGDV) * 2H
D = BCLKX high pulse width = T/2 when CLKGDV is odd or zero and = (CLKGDV/2 + 1) * 2H when CLKGDV is even
FSRP = FSXP = 1. As a SPI master, BFSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on BFSX
and BFSR is inverted before being used internally.
§
CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP
CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP
BFSX 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
(BCLKX).

§
DS refers to the logical OR of HCS, HDS1, and HDS2.
HD refers to any of the HPI data bus pins (HD0, HD1, HD2, etc.). HAD stands for HCNTL0, HCNTL1, and HR/W.
DMAC stands for direct memory access controller (DMAC). The HPI8 shares the internal DMA bus with the DMAC, thus HPI8 access times are
affected by DMAC activity.
NOTES: 1. The HRDY output is always high when the HCS input is high, regardless of DS timings.
2. This timing applies when writing a one to the DSPINT bit or HINT bit of the HPIC register. All other writes to the HPIC occur
asynchronously, and do not cause HRDY to be deasserted.
