Four of PORTB’s pins, RB7:RB4, have an interrupt on change feature. Only pins configured as
inputs can cause this interrupt to occur (i.e. any RB7:RB4 pin configured as an output is excluded
from the interrupt on change comparison). The input pins (of RB7:RB4) are compared with the
old value latched on the last read of PORTB. The “mismatch” outputs of RB7:RB4 are OR’ed
together to generate the RB Port Change Interrupt with flag bit RBIF (INTCON<0>).
This interrupt can wake the device from SLEEP. The user, in the interrupt service routine, can
clear the interrupt in the following manner:
a)
b)
A mismatch condition will continue to set flag bit RBIF. Reading PORTB will end the mismatch
condition, and allow flag bit RBIF to be cleared.
This interrupt on mismatch feature, together with software configurable pull-ups on these four
pins allow easy interface to a keypad and make it possible for wake-up on key-depression.
The interrupt on change feature is recommended for wake-up on key depression and operations
where PORTB is only used for the interrupt on change feature. Polling of PORTB is not recom-
mended while using the interrupt on change feature.

Any read or write of PORTB. This will end the mismatch condition.
Clear flag bit RBIF.
Note 1: I/O pins have diode protection to V
2: To enable weak pull-ups, set the appropriate TRIS bit(s)
3: In sleep mode the device is in Q1 state.
