1.6.5
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.
