14.6.1
RB0/INT INTERRUPT
External interrupt on RB0/INT pin is edge triggered:
either rising if INTEDG bit (OPTION<6>) is set, or
falling, if INTEDG bit is clear. When a valid edge
appears
on
the
RB0/INT
pin,
the
INTF
bit
(INTCON<1>) is set. This interrupt can be disabled by
clearing the INTE control bit (INTCON<4>). The INTF
bit must be cleared in software in the interrupt service
routine before re-enabling this interrupt. The RB0/INT
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. See
Section 14.9 for details on SLEEP, and Figure 14-17
for timing of wake-up from SLEEP through RB0/INT
interrupt.
14.6.2
TMR0 INTERRUPT
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. For operation of the Timer0 module,
14.6.3
PORTB INTERRUPT
An input change on PORTB <7:4> sets the RBIF
(INTCON<0>) bit. The interrupt can be enabled/
disabled by setting/clearing the RBIE (INTCON<4>)
bit. For operation of PORTB (Section 5.2).
14.6.4
COMPARATOR INTERRUPT
See Section 9.6 for complete description of comparator
interrupts.
FIGURE 14-15:
INT PIN INTERRUPT TIMING
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 RBIF inter-
rupt flag may not get set.

Note
1: INTF flag is sampled here (every Q1).
2: Asynchronous interrupt latency = 3-4 Tcy. Synchronous latency = 3 Tcy, where Tcy = instruction cycle time. Latency
is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
3: CLKOUT is available in ER and INTRC Oscillator mode.
4: For minimum width of INT pulse, refer to AC specs.
5: INTF is enabled to be set anytime during the Q4-Q1 cycles.
