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 PORTB change sets the RBIF
(INTCON<0>) bit. The interrupt can be enabled/
disabled by setting/clearing the RBIE (INTCON<3>)
bit. Plus, individual pins can be configured through the
IOCB register.

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
