Legend: u = unchanged, x = unknown, - = unimplemented bit read as '0',

q = value depends on condition.

Note 1: One or more bits in INTCON will be affected (to cause wake-up).

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: Table 8-7 lists the reset value for each specific condition.
