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
IOCBP<7:0>: Interrupt-on-Change Positive Edge Enable bits
1 = Interrupt-on-Change enabled on the pin for a positive going edge. IOCBFx bit and IOCIF flag will
be set upon detecting an edge.
0 = Interrupt-on-Change disabled for the associated pin.

IOCBN<7:0>: Interrupt-on-Change Negative Edge Enable bits
1 = Interrupt-on-Change enabled on the pin for a negative going edge. IOCBFx bit and IOCIF will be
set upon detecting an edge.

-n/n = Value at POR and BOR/Value at all other Resets
HS - Bit is set in hardware
bit 7-0
IOCBF<7:0>: Interrupt-on-Change Flag bits
1 = An enabled change was detected on the associated pin.
Set when IOCBPx = 1 and a rising edge was detected on RBx, or when IOCBNx = 1 and a falling
edge was detected on RBx.
0 = No change was detected, or the user cleared the detected change.
