INTERRUPT CAPTURE REGISTERS
Two registers contain the value of the port that
generated the interrupt:
INTCAP0 contains the value of GP0 at time of
GP0 change interrupt
INTCAP1 contains the value of GP1 at time of
GP1 change interrupt
These registers are ‘read-only’ registers (A write to
these registers is ignored).
