Legend:
Note 1:
u
= unchanged,
x
= unknown,
-
= unimplemented bit, read as ’0’,
q
= value depends on condition.
One or more bits in INTCON and PIR1 will be affected (to cause wake-up).
When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h).
See Table 9-5 for reset value for specific condition.
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
.
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
.
