Legend: u = unchanged, x = unknown, -= unimplemented bit, read as '0', q= value depends on condition
Note 1: One or more bits in INTCON and PIR1 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 8-11 for reset value for specific condition.
