Watchdog Timers High-Impedance Registers

WatchdogHighImp(N )

This register configures port N to go to high impedance when the watchdog timer (WDT)
expires, where N is the port number in hexidecimal. WatchdogHighImp(N) is only valid for
bidirectional ports.
Note Ports can range from 0 to 11 (0x0 to 0xB), depending on your device. For each port,
you must add an additional offset equal to 0x10 time the port number in hex.
Address Offset: 0x46 + 0x(N)0
