Legend: u = unchanged, x = unknown, r = reserved, -= 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 11-5 for reset value for specific condition.
