When the PM12 bit in the PM1 register is set to 1 (reset when watchdog timer underflows), the MCU resets its pins,
CPU, and SFR if the watchdog timer underflows. Then the program beginning with the address indicated by the
reset vector is executed. After reset, the low-speed on-chip oscillator clock divided by 8 is automatically selected as
the CPU clock.
The watchdog timer reset does not reset some SFRs. Refer to 4. Special Function Registers (SFRs) for details.
The internal RAM is not reset. When the watchdog timer underflows, the contents of internal RAM are undefined.
Refer to 13. 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 SFR. The
program beginning with the address indicated by the reset vector is executed. After reset, the low-speed on-chip
oscillator clock divided by 8 is automatically selected for the CPU clock.
The software reset does not reset some SFRs. Refer to 4. Special Function Registers (SFRs) for details.
The internal RAM is not reset.
