Note 1: When the wake-up is due to an interrupt and global enable bit, GIE is set, the PC is loaded with the interrupt vector
(0004h) after execution of PC+1.

Legend: u = unchanged, x = unknown, - = unimplemented bit, reads as ‘0’,q = value depends on condition.
Note 1: If VDD goes too low, Power-on Reset will be activated and registers will be affected differently.
2: One or more bits in INTCON, PIR1 and/or PIR2 will be affected (to cause wake-up).
3: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt
vector (0004h).
4: See Table 9-5 for reset value for specific condition.
