12.4.2
TIMER0 INTERRUPT
An overflow (FFh
→ 00h) in the TMR0 register will set
the T0IF bit of the INTCON register. The interrupt can
be enabled/disabled by setting/clearing T0IE bit of the
INTCON register. See Section 5.0 “Timer0 Module”
for operation of the Timer0 module.
12.4.3
PORTA INTERRUPT-ON-CHANGE
An input change on PORTA sets the RAIF bit of the
INTCON
register.
The
interrupt
can
be
enabled/disabled by setting/clearing the RAIE bit of the
INTCON
register.
Plus,
individual
pins
can
be
configured through the IOCA register.
FIGURE 12-7:
INTERRUPT LOGIC
Note:
If a change on the I/O pin should occur
when any PORTA operation is being
executed, then the RAIF interrupt flag may
not get set.

Note
1:
Some peripherals depend upon the system clock for
operation. Since the system clock is suspended during Sleep, only
those peripherals which do not depend upon the system clock will wake
the part from Sleep. See Section 12.7.1 “Wake-up from Sleep”.
