Legend: u= unchanged, x= unknown, — = unimplemented bit, read as ‘0’, q= value depends on condition.
Note 1: One or more bits in INTCON, PIR1 and PR2 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: See Table 15-3 for Reset value for specific condition.
