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 Ta bl e 9 -5 for Reset value for specific condition.
4: On any device Reset, these pins are configured as inputs.
5: This is the value that will be in the port output latch.
