IOCP<7:0>: Interrupt-on-Change Positive Edge Enable bits
1 = Interrupt-on-change is enabled on the pin for a rising edge; associated status bit and interrupt flag
1 = Interrupt-on-change is enabled on the pin for a rising edge; associated status bit and interrupt flag
will be set upon detecting an edge

IOCF<7:0>: Interrupt-on-Change Flag bits
1 = An enabled change was detected on the associated pin; this is set when IOCP<x> = 1 and a positive
1 = An enabled change was detected on the associated pin; this is set when IOCP<x> = 1 and a positive
edge was detected on the input pin or when IOCN<x> = 1 and a negative edge was detected on the
input pin (clear in software to clear the IOCIF bit)
input pin (clear in software to clear the IOCIF bit)
0 = No change was detected or the user cleared the detected change
