CLR WDT1
Preclear Watchdog Timer
Description
The TD, PD flags, WDT and the WDT Prescaler has cleared (re-counting
from 0), if the other preclear WDT instruction has been executed. Only exe-
cution of this instruction without the other preclear instruction just sets the
indicated flag which implies this instruction has been executed and the TO
and PD flags remain unchanged.
