16.3.1
External interrupt on RB0/INT/SEG0 pin is edge-trig-
gered; either rising if the INTEDG bit of the OPTION
register is set, or falling, if the INTEDG bit is clear.
When a valid edge appears on the RB0/INT/SEG0 pin,
the INTF bit of the INTCON register is set. This inter-
rupt can be disabled by clearing the INTE control bit of
the INTCON register. The INTF bit must be cleared in
software in the Interrupt Service Routine before
re-enabling this interrupt. The RB0/INT/SEG0 interrupt
can wake-up the processor from Sleep if the INTE bit
was set prior to going into Sleep. The status of the GIE
bit decides whether or not the processor branches to
the interrupt vector following wake-up (0004h). See
Section 16.5 “Power-Down Mode (Sleep)” for details
on Sleep and Figure 16-10 for timing of wake-up from
Sleep through RB0/INT/SEG0 interrupt.

16.3.2
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 5.0 “Timer0 Module”
for operation of the Timer0 module.
16.3.3
An input change on PORTB change sets the RBIF bit
of the INTCON register. The interrupt can be
enabled/disabled by setting/clearing the RBIE bit of the
INTCON register. Plus, individual pins can be
configured through the IOCB register.
Note:
* Only available on the PIC16F914/917.
TMR0 INTERRUPT
PORTB 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 RBIF
interrupt flag may not get set.
