SEL0 (Bit 0), SEL1 (Bit 1) and SEL2 (Bit 2)
Use SEL0, SEL1 and SEL2 to select the watchdog timeout time. Writing
to these bits does not clear or reset the watchdog timer. Refer to
WD0 (Bit 3) and WD1 (Bit 4)
Use these bits to define the event that occurs on a watchdog timeout and to
disable the watchdog timer. Reading these bits returns the last value
written. Refer to
