Note:
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 ´ (1/fTP)
01: 211 ´ (1/fTP)
10: 212 ´ (1/fTP)
11: 213 ´ (1/fTP)
WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable
1010: WDT disabled
Other values: WDT enabled - Recommended value is 0101
If the ²watchdog timer enable² 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~WDTEN0¹1010.
