REGISTER 7-1:
IOCBP: INTERRUPT-ON-CHANGE POSITIVE EDGE REGISTER
R/W-0/0
IOCBP7
IOCBP6
IOCBP5
IOCBP4
IOCBP3
IOCBP2
IOCBP1
IOCBP0
bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
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. Associated Status bit and
interrupt 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. Associated Status bit and
interrupt flag will be set upon detecting an edge.
0
= Interrupt-on-Change disabled for the associated pin.

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.
