10.3 Time-out Period
If the WDTCPS bits in CONFIG3 are set to 
   0’b11111, then the WDTPS bits set the time-out period from 1 ms to 256 seconds (nominal). If any
         value other than the default value is assigned to WDTCPS Configuration bits, then the timer
         period will be based on the WDTCPS bits in the CONFIG3 register. After a Reset, the default
         time-out period is 2s.
