CLR WDT1
Preclear watchdog timer
Description
The PD, TO flags and WDT are cleared, if the other preclear WDT in-
struction had been executed. Only execution of this instruction without
the other preclear instruction sets the indicating flag which implies that
this instruction was executed and the PD and TO flags remain un-
changed.
Operation
WDT last two bits
