This bit will enable the generation of a Reset pulse when a Watchdog Timer
time-out occurs.
0 = Disabled
1 = Enabled
These bits store the time-out value of the Watchdog Timer. The scale of the
timer is determined 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 and
generate Reset if RST_EN_WD is enabled.
0 = 150 ms
1 = 2.5 sec
