1.6.9
The INTCAP register captures the GPIO port value at
the time the interrupt occurred. The register is ‘read-
only’ and is updated only when an interrupt occurs. The
register will remain unchanged until the interrupt is
cleared via a read of INTCAP or GPIO.

ICP7:ICP0: These bits reflect the logic level on the port pins at the time of interrupt due to pin
change <7:0>.
1 = Logic-high.
0 = Logic-low.
