When the PM12 bit in the PM1 register is set to 1 (reset when watchdog timer underflows), the MCU resets its pins,
CPU, and SFRs when the watchdog timer underflows. Then the program beginning with the address indicated by
the reset vector is executed. The low-speed on-chip oscillator clock with no division is automatically selected as the
CPU clock after reset.
Refer to 4. Special Function Registers (SFRs) for the status of the SFRs after watchdog timer reset.
The internal RAM is not reset. When the watchdog timer underflows while writing to the internal RAM is in
progress, the contents of internal RAM are undefined.
The underflow period and refresh acknowledge period for the watchdog timer can be set by bits WDTUFS0 and
WDTUFS1 and bits WDTRCS0 and WDTRCS1 in the OFS2 register, respectively.
Refer to 14. Watchdog Timer for details of the watchdog timer.
When the PM03 bit in the PM0 register is set to 1 (MCU reset), the MCU resets its pins, CPU, and SFRs. The
program beginning with the address indicated by the reset vector is executed. The low-speed on-chip oscillator
clock with no division is automatically selected for the CPU clock after reset.
Refer to 4. Special Function Registers (SFRs) for the status of the SFRs after software reset.
The internal RAM is not reset.
