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 conditions.
5: If wake-up was due to comparator input changing , then bit 6 = 1. All other interrupts generating a wake-
up will cause bit 6 = u.
6: If RESET was due to brown-out, then PCON bit0 = 0. All other RESETS will cause bit0 = u.
