INTEG1
unimplemented, read as 0
PFDCS: PFD clock source selection
unimplemented, read as 0
PFDC: I/O or PFD selection
LXTLP: LXT oscillator low power control function
CLKMOD: system clock mode selection
INTEG1, INTEG0: External interrupt edge type
TBSEL1, TBSEL0: Time base period selection
WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable
If the watchdog timer enable 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.
