Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-0
IOCxP<7:0>: Interrupt-on-Change Positive Edge Enable bits
1 = Interrupt-on-Change enabled on the IOCx pin for a positive-going edge. Associated Status bit and interrupt flag
will be set upon detecting an edge.
0 = Interrupt-on-Change disabled for the associated pin.

-n/n = Value at POR and BOR/Value at all other Resets
HS - Bit is set in hardware
bit 7-0
IOCxF<7:0>: Interrupt-on-Change Flag bits
1 = A enabled change was detected on the associated pin. Set when IOCP[n] = 1 and a positive edge was detected
on the IOCn pin, or when IOCN[n] = 1 and a negative edge was detected on the IOCn pin
0 = No change was detected, or the user cleared the detected change
