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 register. Plus, individual pins can be
configured through the IOC register.
FIGURE 17-7: 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.
