INTEG1, INTEG0: External interrupt edge type
00: disable
01: rising edge trigger
10: falling edge trigger
11: dual edge trigger
TBSEL1, TBSEL0: Time base period selection
00: 210 x (1/fTP)
01: 211 x (1/fTP)
10: 212 x (1/fTP)
11: 213 x (1/fTP)
WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable
1010: WDT disabled
Other values: WDT enabled - Recommended value is 0101
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.
Note: 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.
