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: See Table 8-10 for reset value for specific condition.
4: The PCON register is not implemented on the PIC16C71.
5: Brown-out reset is not implemented on the PIC16C71.
