14.3.2
An overflow (FFh → 00h) in the TMR0 register will set
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.

14.3.3
An input change on PORTA or PORTB change sets the
RABIF (INTCON<0>) bit. The interrupt can be enabled/
disabled by setting/clearing the RABIE (INTCON<3>)
bit. Plus, individual pins can be configured through the
IOCA or IOCB registers.

If a change on the I/O pin should occur
when the read operation is being executed
(start of the Q2 cycle), then the RABIF
interrupt flag may not get set. See
Section 4.2.3 “Interrupt-on-change” for
more information.
Some peripherals depend upon the system
clock for operation. Since the system clock is
suspended during Sleep, these peripherals
will not wake the part from Sleep. See
Section 14.6.1 “Wake-up from Sleep”.
