Question:

When the PM12 bit in the PM1 register is set to 1 (reset when watchdog timer underflows) and the watchdog timer underflows, does the watchdog timer stop at this time?

Answer:

The registers associated with the watchdog timer are reset and the watchdog timer count operation stops. However, the watchdog timer automatically restarts when bit 0 of address FFFFFh is set to 0.
