INTCON REGISTER
The INTCON register is a readable and writable
register, which contains the various enable and flag bits
for all interrupt sources except the comparator module.
See
and
for
a
description of the comparator enable and flag bits.
Note:
Interrupt flag bits get set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>).

bit 0:
RBIF: RB Port Change Interrupt Flag bit
1
= When at least one of the RB<7:4> pins changed state (must be cleared in software)
0
= None of the RB<7:4> pins have changed state
