4.2.2.3 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 Section 4.2.2.4 and Section 4.2.2.5 for a
description of the comparator enable and flag bits.
PIC16CE62X
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>).

0 = The RB0/INT external interrupt did not occur
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
