PIC16F87/88
15.10.1
External interrupt on the RB0/INT pin is edge-triggered,
either rising if bit INTEDG (OPTION_REG<6>) is set,
or falling if the INTEDG bit is clear. When a valid edge
appears on the RB0/INT pin, flag bit, INT0IF
(INTCON<1>), is set. This interrupt can be disabled by
clearing enable bit INT0IE (INTCON<4>). Flag bit
INT0IF must be cleared in software in the Interrupt
Service Routine before re-enabling this interrupt. The
INT interrupt can wake-up the processor from Sleep, if
bit INT0IE was set prior to going into Sleep. The status
of global interrupt enable bit GIE decides whether or
not the processor branches to the interrupt vector,
following wake-up. See Section 15.13 “Power-Down
Mode (Sleep)” for details on Sleep mode.
15.10.2
An overflow (FFh
flag bit TMR0IF (INTCON<2>). The interrupt can be
enabled/disabled by setting/clearing enable bit TMR0IE
(INTCON<5>), see Section 6.0 “Timer0 Module”.

15.10.3
An input change on PORTB<7:4> sets flag bit RBIF
(INTCON<0>). The interrupt can be enabled/disabled
by setting/clearing enable bit RBIE (INTCON<4>), see
Section 3.2 “EECON1 and EECON2 Registers”.
15.11 Context Saving During Interrupts
During an interrupt, only the return PC value is saved on
the stack. Typically, users may wish to save key registers
during an interrupt (i.e., W, STATUS registers).
Since the upper 16 bytes of each bank are common in
the PIC16F87/88 devices, temporary holding registers
W_TEMP,
should be placed in here. These 16 locations don’t
require banking and therefore, make it easier for
context save and restore. The same code shown in
Example 15-1 can be used.
