Legend: u = unchanged, x = unknown, - = unimplemented bit, read as ’0’, q = value depends on condition,
r = reserved, maintain clear
Note 1: One or more bits in INTCON, PIR1 and/or PIR2 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 12-5 for RESET value for specific condition.
