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 7-6
bit 5-0
Unimplemented: Read as ‘0’
IOCCN<5:0>: 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.

IOCCF<5:0>: Interrupt-on-Change Flag bits
1 = An enabled change was detected on the associated pin.
Set when IOCCPx = 1 and a rising edge was detected on RBx, or when IOCCNx = 1 and a falling
edge was detected on RCx.
0 = No change was detected, or the user cleared the detected change.
