Note: When selecting the Interrupt Mode, always disable interrupts prior to changing or setting states. This will
help prevent inadvertent or un-expected interrupts from occurring. When using the high and low level interrupts, a
change in state of the input must occur before the interrupt can be cleared. The device providing the input to Base
+0, bit D0 must do this.
PAD0-7
= Port A (Base+0) Input port.
PCD0-7
= Port C (Base+2) Output port.
IRC0-1= Interrupt Mode select (Base+5)
IRQEN = enable interrupts (Base+5)
0 = disabled
1 = enabled (disabled after reset or power up).
IRQST = interrupt status (Base+5)
1 = interrupt pending (reading the bit clears interrupt).
