These bits store the time-out value of the Watchdog Timer.
The scale of the timer is determine by the pre-scaler. The
timer can support a value of 150 ms to 4.8 sec when the
pre-scaler 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 and generate Reset if RST_EN_WD is enabled.
