16.4.1
External interrupt on RB0/INT/SEG0 pin is edge-trig-
gered; either rising if the INTEDG bit (OPTION<6>) is
set, or falling, if the INTEDG bit is clear. When a valid
edge appears on the RB0/INT/SEG0 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
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 16.7 “Power-Down
Mode (Sleep)” for details on Sleep and Figure 16-10
for
RB0/INT/SEG0 interrupt.
