It should also be taken into account that under worst
case conditions (V
max. WDT prescaler), it may take several seconds
before a WDT time-out occurs.

Note:
Note: PSA and PS2:PS0 are bits in the OPTION register.
When a CLRWDT instruction is executed
and the prescaler is assigned to the WDT,
the prescaler count will be cleared, but the
prescaler assignment is not changed.
