WDT Reset during normal operation
WDT Wake-up from SLEEP
Interrupt wake-up from SLEEP
Legend: u = unchanged, x = unknown, - = unimplemented bit read as ’0’.
Note 1: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h).

2: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h).
3: See Table 9-5 for reset value for specific condition.
4: If wake-up was due to A/D completing then bit 6 = 1, all other interrupts generating a wake-up will cause bit 6 = u.
5: If wake-up was due to A/D completing then bit 3 = 0, all other interrupts generating a wake-up will cause bit 3 = u.
