17.4.2

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 6.0 “Timer0 Module”

for operation of the Timer0 module.

17.4.3

PORTA INTERRUPT-ON-CHANGE

An input change on PORTA sets the IOCIF bit of the

INTCON register. The interrupt can be enabled/

disabled by setting/clearing the IOCIE bit of the

INTCON

Plus,

individual

pins

can

configured through the IOC register.

INTERRUPT LOGIC

Note:

If a change on the I/O pin should occur

when any PORTA operation is being

executed, then the IOCIF interrupt flag

may not get set.
