Legend: u = unchanged, x = unknown, - = unimplemented bit, read as '0', q = value depends on condition
Note 1: One or more bits in INTCON and/or 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 14-5 for reset value for specific condition.
4: Bits PIE1<6> and PIR1<6> are reserved on the PIC16C923, always maintain these bits clear.
5: PORTA values when read.
