pin-to-pin and function compatible with the NuMicro Mini51 series, ® ® the 32-bit microcontroller (MCU) embedded with the ARM Cortex -M0 core. The Mini58 series can bridge the gap and replace the cost equivalent to traditional 8- and 16-bit microcontroller by 32-bit performance and rich functions. The Mini58 series supports a wide range of applications from low-end, price sensitive designs to computing-intensive ones and provides advanced highend features in economical products. The Mini58 series can run up to 50 MHz which is faster than 24 MHz in Mini51 series, and operate at a wide voltage range of 2.5V ~ 5.5V and temperature range of -40℃ ~ +105℃. For the Mini58 series, the embedded program flash size upgrades from 16 Kbytes to 32 Kbytes and SRAM upgrades from 2 Kbytes to 4 Kbytes. The Mini58 series also offers size configurable Data Flash (shared with program flash), and 2.5 Kbytes flash for the ISP. The Mini58 series has many high-performance peripheral functions, such as 22.1184 MHz internal RC oscillator (±1% accuracy), I/O port with up to 30 pins, four 32-bit timers, two UARTs 2 with the RS485 function and IrDA function interface, one SPI interface, two I C interfaces, up to three 16-bit PWM generators providing six channels, an 8-channel 10-bit ADC, Watchdog Timer, Window Watchdog Timer, two Analog Comparators and a Brown-out Detector. All these peripherals have been incorporated into the Mini58 series to reduce component count, board space and system cost. Compared to the Mini51 series, the Mini58 series supports additional one 2 UART and one I C interface for better and more flexible connectivity applications. Additionally, the Mini58 series is equipped with ISP (In-System Programming) and ICP (In-Circuit Programming) functions, which allow the user to update the program memory without removing the chip from the actual end product. The Mini58 series also supports In-Application-Programming (IAP) function, user switches the code executing without the chip reset after the embedded flash updated.

Table 6.2-1 Reset Value of Registers 6.2.2.1 nRESET Reset The nRESET reset means to generate a reset signal by pulling low nRESET pin, which is an asynchronous reset input pin and can be used to reset system at any time. When the nRESET voltage is lower than 0.2 VDD and the state keeps longer than 36 us (glitch filter), chip will be reset. The nRESET reset will control the chip in reset state until the nRESET voltage rises above 0.7 VDD and the state keeps longer than 36 us (glitch filter). The PINRF (SYS_RSTSTS[1]) will be set to 1 if the previous reset source is nRESET reset. Figure 6.2-2 shows the nRESET reset waveform.

When applying the power to MCU, the POR module will detect the rising voltage and generate reset signal to system until the voltage is ready for MCU operation. At POR reset, the PORF (SYS_RSTSTS[0]) will be set to 1 to indicate there is a POR reset event. The PORF (SYS_RSTSTS[0]) bit can be cleared by writing 1 to it.

When the AVDD voltage is lower than VLVR and the state keeps longer than De-glitch time (16*HCLK cycles), chip will be reset. The LVR reset will control the chip in reset state until the AVDD voltage rises above VLVR and the state keeps longer than De-glitch time.

This is the result of the CPU being locked because of an unrecoverable exception following the activation of the processor’s built in system state protection hardware. When chip enters debug mode, the CPU lockup reset will be ignored. 6.2.2.7 CPU Reset, CHIP Reset and SYSTEM Reset ® The CPU Reset means only Cortex -M0 core is reset and all other peripherals remain the same status after CPU reset.

To automatically recover the MCU from failure status is one way to improve system reliability. The watch dog timer (WDT) is widely used to check if the system works fine. If the MCU is crashed or out of control, it may cause the watch dog time-out. User may decide to enable system reset during watch dog time-out to recover the system and take action for the system crash/out-of-control after reset. MINI58DE (FMC_ISPCTL[1]) bit is automatically reloaded from CONFIG setting. User can set the CHIPRST (SYS_IPRST0[0]) to 1 to assert the CHIP Reset signal. The MCU Reset is similar with CHIP Reset. The difference is that BS (FMC_ISPCTL[1]) will not be reloaded from CONFIG setting and keep its original software setting for booting from APROM or LDROM. User can set the SYSRESETREQ (SCS_AIRCR[2]) to 1 to assert the MCU Reset. 6.2.3 Power Modes and Wake-up Sources There are several wake-up sources in Idle mode and Power-down mode.

AVDD must be equal to VDD to avoid leakage current.  Digital power from VDD and VSS supplies power to the I/O pins and internal regulator which provides a fixed 1.8V power for digital operation.  Built-in a capacitor for internal voltage regulator The output of internal voltage regulator, LDO_CAP, requires an external capacitor which should be located close to the corresponding pin. Analog power (AVDD) should be the same voltage level as the digital power (VDD). Figure 6.2-7 shows the power distribution of the Mini58 series.

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 zero, and reload (wrap) to the value in the SysTick Reload Value Register (SYST_RVR) on the next clock edge, and then decrement on subsequent clocks. When the counter transitions to zero, 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 zero before enabling the feature. This ensures the timer to count from the SYST_RVR value rather than an arbitrary value when it is enabled. If the SYST_RVR is zero, the timer will be maintained with a current value of zero after it is reloaded with this value. This mechanism can be used to disable the feature independently from the timer enable bit.

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. 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 ® Manual” and “ARM v6-M Architecture Reference Manual”. 6.2.8.3 ® ® Cortex -M0 Technical Reference Exception Model and System Interrupt Map ® The following table lists the exception model supported by NuMicro Mini58 series. 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 the priority 0 is treated as the fourth priority on the system, after three system exceptions “Reset”, “NMI” and “Hard Fault”. Dec. 09, 2015 Page 39 of 83 Rev.1.02 MINI58DE SERIES DATASHEET 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. MINI58DE Exception Name Vector Number Priority Reset 1 -3 NMI 2 -2 Hard Fault 3 -1 Reserved 4 ~ 10 Reserved SVCall 11 Configurable Reserved 12 ~ 13 Reserved PendSV 14 Configurable SysTick 15 Configurable Interrupt (IRQ0 ~ IRQ31) 16 ~ 47 Configurable Table 6.2-7 Exception Model Exception Number Interrupt Number (Bit In Interrupt Interrupt Name Registers) Source Module 1 ~ 15 - - - 16 0 BODOUT Brown-out 17 1 WDT_INT 18 2 19 Interrupt Description System exceptions Power-Down Wake-Up - MINI58DE SERIES DATASHEET Brown-out low voltage detected interrupt Yes WDT Watchdog Timer interrupt Yes EINT0 GPIO External signal interrupt from P3.2 pin Yes 3 EINT1 GPIO External signal interrupt from P5.2 pin Yes 20 4 GP0/1_INT GPIO External signal interrupt from GPIO group P0~P1 Yes 21 5 GP2/3/4_INT GPIO External signal interrupt from GPIO group P2~P4 except P3.2 Yes 22 6 PWM_INT PWM PWM interrupt No 23 7 BRAKE_INT PWM PWM Brake interrupt No 24 8 TMR0_INT TMR0 Timer 0 interrupt Yes 25 9 TMR1_INT TMR1 Timer 1 interrupt Yes 26 ~ 27 10 ~ 11 - - 28 12 UART0_INT UART0 UART0 interrupt Yes 29 13 UART1_INT UART1 UART1 interrupt Yes 30 14 SPI_INT SPI SPI interrupt No 31 15 - - 32 16 GP5_INT GPIO External signal interrupt from GPIO group P5 except P5.2 Yes 33 17 HIRC_TRIM_IN T HIRC HIRC trim interrupt No 34 18 I2C0_INT I2C0 I C0 interrupt Dec. 09, 2015 - - 2 Page 40 of 83 Yes Rev.1.02 MINI58DE Exception Number Interrupt Number (Bit In Interrupt Interrupt Name Registers) Source Module Interrupt Description I2C1 interrupt Power-Down Wake-Up 35 19 I2C1_INT I2C1 36 ~ 40 20 ~ 24 - - 41 25 ACMP_INT ACMP 42 ~ 43 26 ~ 27 - - 44 28 PWRWU_INT CLKC Clock controller interrupt for chip wakeup from Power-down state Yes 45 29 ADC_INT ADC ADC interrupt No 46 ~ 47 30 ~ 31 - - No Analog Comparator 0 or Comparator 1 interrupt Yes - - Table 6.2-8 System Interrupt Map Vector Table 6.2.8.4 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.

Vector Table Word Offset (Bytes) 0x00 Initial Stack Pointer Value Exception Entry Pointer using that Exception Number Table 6.2-9 Vector Table Format 6.2.8.5 Operation Description NVIC interrupts can be enabled and disabled by writing to their corresponding Interrupt SetEnable or Interrupt Clear-Enable register bit-field. The registers use a write-1-to-enable and write1-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 be activated. 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.

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 PDEN (CLK_PWRCTL[7]) bit is set to 1. After that, chip enters Power-down mode and waits for wake-up interrupt source triggered to exit Power-down mode. In Power-down mode, the clock controller turns off the 4~24 MHz external high speed crystal (HXT) and 22.1184 MHz internal high speed RC oscillator (HIRC) to reduce the overall system power consumption. The following figures show the clock generator and the overview of the clock source control.

For instance, the system needs an accurate 22.1184 MHz clock. In such case, if users do not want to use 22.1184 MHz HXT as the system clock source, they need to solder 32.768 kHz crystal in system, and set FREQSEL (SYS_IRCTCTL[0] trim frequency selection) to “1”, and the auto-trim function will be enabled. Interrupt status bit FREQLOCK (SYS_IRCTISTS[0] HIRC frequency lock status) high indicates the HIRC output frequency is accurate within 1% deviation. To get better results, it is recommended to set both LOOPSEL (SYS_IRCTCTL[5:4] trim calculation loop) and RETRYCNT (SYS_IRCTCTL[7:6] trim value update limitation count) to “11”. 6.3.3 System Clock and SysTick Clock The system clock has 4 clock sources which were generated from clock generator block.

The I/O type of each pin can be configured by software individually as Input, Push-pull output, Open-drain output, or Quasi-bidirectional mode. After the chip is reset, the I/O mode of all pins is stay in input mode and each port data register Px_DOUT[n] resets to 1. For Quasi-bidirectional mode, each I/O pin is equipped with a very weak individual pull-up resistor about 110 k ~ 300 k for VDD is from 5.0 V to 2.5 V. 6.5.2 Features  Four I/O modes:  Quasi-bidirectional mode  Push-pull output  Open-drain output  Input-only with high impendence   I/O pin internal pull-up resistor enabled only in Quasi-bidirectional I/O mode  Enabling the pin interrupt function will also enable the pin wake-up function  High driver and high sink I/O mode support  Configurable default I/O mode of all pins after reset by CIOINI (Config0[10]) setting  CIOINI = 0, all GPIO pins in Quasi-bidirectional mode after chip reset  CIOINI = 1, all GPIO pins in Input tri-state mode after chip reset Dec. 09, 2015 Page 51 of 83 Rev.1.02 MINI58DE SERIES DATASHEET  Quasi-bidirectional TTL/Schmitt trigger input mode selected by SYS_Px_MFP[23:16] I/O pin configured as interrupt source with edge/level setting MINI58DE 6.6 Timer Controller (TMR) 6.6.1 Overview The Timer Controller includes two 32-bit timers, TMR0 and TMR1, allowing user to easily implement a timer control for applications.

The PWM0 supports six PWM generators which can be configured as six independent PWM outputs, PWM0_CH0~PWM0_CH5, or as three complementary PWM pairs, (PWM0_CH0, PWM0_CH1), (PWM0_CH2, PWM0_CH3) and (PWM0_CH4, PWM0_CH5) with three programmable dead-time generators. Every complementary PWM pairs share one 8-bit prescaler. There are six clock dividers providing five divided frequencies (1, 1/2, 1/4, 1/8, 1/16) for each channel. Each PWM output has independent 16-bit counter for PWM period control, and 16-bit comparators for PWM duty control. The six PWM generators provide twelve independent PWM interrupt flags which are set by hardware when the corresponding PWM period counter comparison matched period and duty. Each PWM interrupt source with its corresponding enable bit can request PWM interrupt. The PWM generators can be configured as One-shot mode to produce only one PWM cycle signal or Auto-reload mode to output PWM waveform continuously. To prevent PWM driving output pin with unsteady waveform, the 16-bit period down counter and 16-bit comparator are implemented with double buffer. When user writes data to counter/comparator buffer registers, the updated value will be loaded into the 16-bit down counter/ comparator at the end of current period. The double buffering feature avoids glitch at PWM outputs. Besides PWM, Motor controlling also need Timer, ACMP and ADC to work together. In order to control motor more precisely, we provide some registers that not only configure PWM but also Timer, ADC and ACMP, by doing so, it can save more CPU time and control motor with ease especially in BLDC. 6.7.2 Features  Six independent 16-bit PWM duty control units with maximum six port pins:  Six independent PWM outputs – PWM0_CH0, PWM0_CH1, PWM0_CH2, PWM0_CH3, PWM0_CH4, and PWM0_CH5  Three complementary PWM pairs, with each pin in a pair mutually complement to each other and capable of programmable dead-time insertion – (PWM0_CH0, PWM0_CH1), (PWM0_CH2, PWM0_CH3) and (PWM0_CH4, PWM0_CH5)  Three synchronous PWM pairs, with each pin in a pair in-phase – (PWM0_CH0, PWM0_CH1), (PWM0_CH2, PWM0_CH3) and (PWM0_CH4, PWM0_CH5)  Group control bit – PWM0_CH2 and PWM0_CH4 are synchronized with PWM0_CH0, PWM0_CH3 and PWM0_CH5 are synchronized with PWM0_CH1  One-shot (only support edge-aligned type) or Auto-reload mode PWM  Up to 16-bit resolution  Supports edge-aligned, center-aligned and precise center-aligned mode  Supports asymmetric PWM generating in center-aligned and precise center-aligned mode  Supports center loading in center-aligned and precise center-aligned mode  Programmable dead-time insertion between complementary paired PWMs Dec. 09, 2015 Page 53 of 83 Rev.1.02 MINI58DE SERIES DATASHEET The PWM0 supports the following features: MINI58DE  Each pin of PWM0_CH0 to PWM0_CH5 has independent polarity setting control  Hardware fault brake protections  Supports software trigger  Two Interrupt source types:  Synchronously requested at PWM frequency when down counter comparison matched (edge- and center-aligned type) or underflow (edgealigned type)  Requested when external fault brake asserted  BKP0: EINT0 or CPO1  BKP1: EINT1 or CPO0  The PWM signals before polarity control stage are defined in the view of positive logic.
