12.9.2 TIMER INTERRUPT
An overflow (FFh â 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 âTimer0 Moduleâ
for operation of the Timer0 module.

12.9.3 PORTA INTERRUPT
An input change on PORTA change 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.
Note:
If a change on the I/O pin should occur
when the read operation is being executed
(start of the Q2 cycle), then the RAIF
interrupt flag may not get set.
