Shaded cells are not used by the Watchdog Timer.
See Register 12-1 for operation of all Configuration Word register bits.
If WDTE Configuration bit = 1, then WDT is always enabled, irrespective of this control bit. If WDTE
Configuration bit = 0, then it is possible to turn WDT on/off with this control bit.
