CLR WDT1
Preclear watchdog timer
Description
The TD, PD flags and WDT are all cleared (re-counting from zero), if the
other preclear WDT instruction has been executed. Only execution of this in-
struction without the other preclear instruction sets the indicated flag which
implies that this instruction has been executed and the TO and PD flags re-
main unchanged.
