6.2.3 System Power Distribution
In this chip, the power distribution is divided into three segments.
Analog power from AVDD and AVSS provides the power for analog components
operation.
Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 1.8 V power for digital operation and I/O pins.
The outputs of internal voltage regulators, LDO, require an external capacitor which should be
located close to the corresponding pin. Analog power (AVDD) should be the same voltage level
with the digital power (VDD). Figure 6-2 shows the NuMicro® NUC029LDE/NUC029SDE power
distribution.

6.2.5 System Timer (SysTick)
The Cortex® -M0 includes an integrated system timer, SysTick, which provides a simple, 24-bit
clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism. The
counter can be used as a Real Time Operating System (RTOS) tick timer or as a simple counter.
When system timer is enabled, it will count down from the value in the SysTick Current Value
Register (SYST_CVR) to 0, and reload (wrap) to the value in the SysTick Reload Value Register
(SYST_RVR) on the next clock cycle, then decrement on subsequent clocks. When the counter
transitions to 0, the COUNTFLAG status bit is set. The COUNTFLAG bit clears on reads.
The SYST_CVR value is unknown on reset. Software should write to the register to clear it to 0
before enabling the feature. This ensures the timer will count from the SYST_RVR value rather
than an arbitrary value when it is enabled.
If the SYST_RVR is 0, the timer will be maintained with a current value of 0 after it is reloaded
with this value. This mechanism can be used to disable the feature independently from the timer
enable bit.
For more detailed information, please refer to the “ARM® Cortex® -M0 Technical Reference
Manual” and “ARM® v6-M Architecture Reference Manual”.

6.2.6 Nested Vectored Interrupt Controller (NVIC)
The Cortex® -M0 provides an interrupt controller as an integral part of the exception mode, named
as “Nested Vectored Interrupt Controller (NVIC)”, which is closely coupled to the processor core
and provides following features:
Nested and Vectored interrupt support
Automatic processor state saving and restoration
Reduced and deterministic interrupt latency
The NVIC prioritizes and handles all supported exceptions. All exceptions are handled in “Handler
Mode”. This NVIC architecture supports 32 (IRQ[31:0]) discrete interrupts with 4 levels of priority.
All of the interrupts and most of the system exceptions can be configured to different priority
levels. When an interrupt occurs, the NVIC will compare the priority of the new interrupt to the
current running one’s priority. If the priority of the new interrupt is higher than the current one, the
new interrupt handler will override the current handler.
When an interrupt is accepted, the starting address of the interrupt service routine (ISR) is fetched
from a vector table in memory. There is no need to determine which interrupt is accepted and
branch to the starting address of the correlated ISR by software. While the starting address is
fetched, NVIC will also automatically save processor state including the registers “PC, PSR, LR,
R0~R3, R12” to the stack. At the end of the ISR, the NVIC will restore the mentioned registers
from stack and resume the normal execution. Thus it will take less and deterministic time to
process the interrupt request.
The NVIC supports “Tail Chaining” which handles back-to-back interrupts efficiently without the
overhead of states saving and restoration and therefore reduces delay time in switching to
pending ISR at the end of current ISR. The NVIC also supports “Late Arrival” which improves the
efficiency of concurrent ISRs. When a higher priority interrupt request occurs before the current
ISR starts to execute (at the stage of state saving and starting address fetching), the NVIC will
give priority to the higher one without delay penalty. Thus it advances the real-time capability.
For more detailed information, please refer to the “ARM® Cortex® -M0 Technical Reference
Manual” and “ARM® v6-M Architecture Reference Manual”.

6.2.6.1 Exception Model and System Interrupt Map
The following table lists the exception model supported by NuMicro® NUC029LDE/NUC029SDE.
Software can set four levels of priority on some of these exceptions as well as on all interrupts.
The highest user-configurable priority is denoted as “0” and the lowest priority is denoted as “3”.
The default priority of all the user-configurable interrupts is “0”. Note that priority “0” is treated as
the fourth priority on the system, after three system exceptions “Reset”, “NMI” and “Hard Fault”.

6.2.6.2 Vector Table
When an interrupt is accepted, the processor will automatically fetch the starting address of the
interrupt service routine (ISR) from a vector table in memory. For ARMv6-M, the vector table base
address is fixed at 0x00000000. The vector table contains the initialization value for the stack
pointer on reset, and the entry point addresses for all exception handlers. The vector number on
previous page defines the order of entries in the vector table associated with exception handler
entry as illustrated in previous section.

6.2.6.3 Operation Description
NVIC interrupts can be enabled and disabled by writing to their corresponding Interrupt Set-
Enable or Interrupt Clear-Enable register bit-field. The registers use a write-1-to-enable and write-
1-to-clear policy, both registers reading back the current enabled state of the corresponding
interrupts. When an interrupt is disabled, interrupt assertion will cause the interrupt to become
Pending, however, the interrupt will not activate. If an interrupt is Active when it is disabled, it
remains in its Active state until cleared by reset or an exception return. Clearing the enable bit
prevents new activations of the associated interrupt.
NVIC interrupts can be pended/un-pended using a complementary pair of registers to those used
to enable/disable the interrupts, named the Set-Pending Register and Clear-Pending Register
respectively. The registers use a write-1-to-enable and write-1-to-clear policy, both registers
reading back the current pended state of the corresponding interrupts. The Clear-Pending
Register has no effect on the execution status of an Active interrupt.
NVIC interrupts are prioritized by updating an 8-bit field within a 32-bit register (each register
supporting four interrupts).
The general registers associated with the NVIC are all accessible from a block of memory in the
System Control Space and will be described in next section.

6.3 Clock Controller
6.3.1 Overview
The clock controller generates the clocks for the whole chip, including system clocks and all
peripheral clocks. The clock controller also implements the power control function with the
individually clock ON/OFF control, clock source selection and clock divider. The chip enters
Power-down mode when Cortex® -M0 core executes the WFI instruction only if the
PWR_DOWN_EN (PWRCON[7]) bit and PD_WAIT_CPU (PWRCON[8]) bit are both set to 1.
After that, chip enters Power-down mode and wait for wake-up interrupt source triggered to leave
Power-down mode. In the Power-down mode, the clock controller turns off the 4~24 MHz external
high speed crystal oscillator and 22.1184 MHz internal high speed RC oscillator to reduce the
overall system power consumption. The following figures show the clock generator and the
overview of the clock source control.
The clock generator consists of 5 clock sources as listed below:
4~24 MHz external high speed crystal oscillator (HXT)
Programmable PLL output clock frequency(PLL FOUT),PLL source can be from
external 4~24 MHz external high speed crystal oscillator (HXT) or 22.1184 MHz

6.3.4 Frequency Divider Output
This device is equipped with a power-of-2 frequency divider which is composed by16 chained
divide-by-2 shift registers. One of the 16 shift register outputs selected by a sixteen to one
multiplexer is reflected to CLKO function pin. Therefore there are 16 options of power-of-2 divided
clocks with the frequency from Fin/21 to Fin/216 where Fin is input clock frequency to the clock
divider.
The output formula is Fout = Fin/2(N+1), where Fin is the input clock frequency, Fout is the clock
divider output frequency and N is the 4-bit value in FSEL (FRQDIV[3:0]).
When writing 1 to DIVIDER_EN (FRQDIV[4]), the chained counter starts to count. When writing 0
to DIVIDER_EN (FRQDIV[4]), the chained counter continuously runs till divided clock reaches low
state and stay in low state.
If DIVIDER1(FRQDIV[5]) is set to 1, the frequency divider clock (FRQDIV_CLK) will bypass
power-of-2 frequency divider. The frequency divider clock will be output to CLKO pin directly.

6.4 Flash Memory Controller (FMC)
6.4.1 Overview
The NuMicro® NUC029LDE/NUC029SDE has 68 Kbytes on-chip embedded Flash for application
program memory (APROM) that can be updated through ISP procedure. The In-System-
Programming (ISP) function enables user to update program memory when chip is soldered on
PCB. After chip is powered on, Cortex® -M0 CPU fetches code from APROM or LDROM decided
by boot select (CBS) in CONFIG0. By the way, the NuMicro® NUC029LDE/NUC029SDE also
provides additional Data Flash for user to store some application dependent data.
The NuMicro® NUC029LDE/NUC029SDE supports another flexible feature: configurable Data
Flash size. The Data Flash size is decided by Data Flash variable size enable (DFVSEN), Data
Flash enable (DFEN) in Config0 and Data Flash base address (DFBADR) in Config1. When
DFVSEN is set to 1, the Data Flash size is fixed at 4K and the address is started from
0x0001_f000, and the APROM size is become 64K. When DFVSEN is set to 0 and DFEN is set to
1, the Data Flash size is zero and the APROM size is 68 Kbytes. When DFVSEN is set to 0 and
DFEN is set to 0, the APROM and Data Flash share 68 Kbytes continuous address and the start
address of Data Flash is defined by (DFBADR) in Config1.

Note:
1. nRESET pin is a Schmitt trigger input.
2. Crystal Input is a CMOS input.
3. Pins of PA, PB, PC, PD, PE and PF can source a transition current when they are being externally driven from 1 to 0. In the
condition of VDD = 5.5 V, the transition current reaches its maximum value when VIN approximates to 2 V.

2. HCLK must be higher than 2 MHz to achieve the maximum standard mode I2C frequency. It must be higher than 8 MHz to
achieve the maximum fast mode I2C frequency.
3. I2C controller must be retriggered immediately at slave mode after receiving STOP condition.
4. The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the undefined region of
the falling edge of SCL.
5. The maximum hold time of the Start condition has only to be met if the interface does not stretch the low period of SCL
