The INTCON register controls how the associated pin
value is compared for the interrupt-on-change feature.
If a bit is set, the corresponding I/O pin is compared
against the associated bit in the DEFVAL register. If a
bit value is clear, the corresponding I/O pin is
compared against the previous value.

INTERRUPT CONTROL (INTCON)
REGISTER
INTCON – INTERRUPT-ON-CHANGE CONTROL REGISTER (ADDR 0x04)
IOC7:IOC0: These bits control how the associated pin value is compared for interrupt-on-
change <7:0>.
1 = Controls how the associated pin value is compared for interrupt-on-change.
0 = Pin value is compared against the previous pin value.
Refer to INTCON and GPINTEN.
