These bits store the time-out value of the Watchdog
timer. The scale of the timer is determine by the
prescaler.
The timer can support a value of 150 ms to 4.8 sec
when the prescaler is set to 150 ms. If the prescaler
is set to 2.5 sec, it can support a value from 2.5 sec
to 80 sec.
When the Watchdog timer reaches
“
0
”
, it will set the
WD_TO_STATUS bit.
