Preliminary

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

the IOCA register.

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

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”.
