Legend: u = unchanged, x = unknown, - = unimplemented bit, reads as ‘0’, q = value depends on condition.
Note 1: If V
Register
2: One or more bits in INTCON and/or PIR1 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
4: See Table 9-6 for RESET value for specific condition.
5: If wake-up was due to data EEPROM write completing, bit 7 = 1; A/D conversion completing, bit 6 = 1;
6: If RESET was due to brown-out, then bit 0 = 0. All other RESETS will cause bit 0 = u.

Comparator input changing, bit 3 = 1; or Timer1 rolling over, bit 0 = 1. All other interrupts generating a
wake-up will cause these bits to = u.

goes too low, Power-on Reset will be activated and registers will be affected differently.
