INTEG1
INTEG1, INTEG0: External interrupt edge type
TBSEL1, TBSEL0: Time base period selection
WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable
If the watchdog timer enable is configuration option is selected, then the watchdog
timer will always be enabled and the WDTEN3~WDTEN0 control bits will have no
effect.
The WDT is only disabled when both the WDT configuration option is disabled and
when bits WDTEN3~WDTEN0=1010.
The WDT is enabled when either the WDT configuration option is enabled or when
bits WDTEN3~WDTEN0 1010.
Unimplemented, read as 0
