R5F21322芯片概述：
Watchdog Timer Reset
Where the PM12 bit in the PM1 register is “1” (reset when watchdog timer underflows), the microcomputer initializes its pins, CPU and SFR if the watchdog timer underflows. Then the program is executed
starting from the address indicated by the reset vector.
At watchdog timer reset, some SFR’s are not initialized. Refer to “SFR”. Also, since the PM01 to PM00 bits in the PM0 register are not initialized, the processor mode remains unchanged.
Where the R5F21322 CPU clock source is changed from the On-chip Oscillator to the main clock, change the operation mode to the medium speed mode (divided by 8 mode) after the clock was divided by 8 (the CM06 bit of CM0 register was set to “1”) in the On-chip Oscillator mode.
- High-speed Mode
The main clock divided by 1 provides the CPU clock.
- Medium-speed Mode
The main clock divided by 2, 4, 8 or 16 provides the CPU clock.
- On-chip Oscillator Mode
The On-chip Oscillator clock divided by 1 (undivided), 2, 4, 8 or 16 provides the CPU clock. The Onchip Oscillator clock is also the clock source for the peripheral function clocks.
The microcomputer is moved out of wait mode by a hardware reset or peripheral function interrupt.If the microcomputer is to be moved out of exit wait mode by a hardware reset, set the peripheral function interrupt priority ILVL2 to ILVL0 bits to “0002” (interrupts disabled) before executing the WAIT instruction.
The peripheral function interrupts are affected by the CM02 bit. If CM02 bit is “0” (peripheral function clocks not turned off during wait mode), all peripheral function interrupts can be used to exit wait
mode. If CM02 bit is “1” (peripheral function clocks turned off during wait mode), the peripheral functions using the peripheral function clocks stop operating, so that only the peripheral functions clocked
