Watchdog Input Selection:
00 = GPI1 input
01 = GPI2 input
10 = GPI3 input
11 = GPI4 input (MAX6889/MAX6890 only). Selects GPI3 on MAX6891.

Watchdog Internal Input Selection:
0000 = PO1
0001 = PO2
0010 = PO3
0011 = PO4
0100 = PO5
0101 = PO6 (MAX6889/MAX6890 only)
0110 = PO7 (MAX6889/MAX6890 only)
0111 = PO8 (MAX6889/MAX6890 only)
1000 = PO9 (MAX6889 only)
