Note 1:
If V
DD
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 9-6 for reset value for specific condition.
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 bit 0 = 0. All other resets will cause bit 0 = u.
