Legend: u = unchanged, x = unknown, - = unimplemented bit read as ’0’.

Note 1:

When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h).

Legend: u = unchanged,

= unknown,

= unimplemented bit, read as ’0’, q = value depends on condition.

Note 1:

One or more bits in INTCON and PIR1 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 9-5 for reset value for specific condition.

4: If wake-up was due to A/D completing then bit 6 = 1, all other interrupts generating a wake-up will cause bit 6 = u.

5: If wake-up was due to A/D completing then bit 3 = 0, all other interrupts generating a wake-up will cause bit 3 = u.
