WATCHDOG TIMER
WATCHDOG TIMER DATA (WTDAT) REGISTER
The WTDAT register is used to specify the time-out duration. The content of WTDAT cannot be automatically loaded
into the timer counter at initial watchdog timer operation. However, using 0x8000 (initial value) will drive the first time-
out. In this case, the value of WTDAT will be automatically reloaded into WTCNT.
WATCHDOG TIMER COUNT (WTCNT) REGISTER
The WTCNT register contains the current count values for the watchdog timer during normal operation. Note that the
content of the WTDAT register cannot be automatically loaded into the timer count register when the watchdog timer
is enabled initially, so the WTCNT register must be set to an initial value before enabling it.
