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.
