An overflow (FFh
the T0IF (INTCON<2>) bit. The interrupt can be
enabled/disabled by setting/clearing T0IE (INTCON<5>)
bit. See Section 5.0 “Timer0 Module” for operation of
the Timer0 module.

12.9.3
An input change on PORTA change sets the RAIF
(INTCON<0>) bit. The interrupt can be enabled/
disabled by setting/clearing the RAIE (INTCON<3>)
bit. Plus, individual pins can be configured through the
IOCA register.
Note:
PORTA INTERRUPT
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.
