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 7-4

IOCBN<7:4>: Interrupt-on-Change PORTB Negative Edge Enable bits

1 = Interrupt-on-Change enabled on the pin for a negative going edge. IOCBFx bit and IOCIF flag will

be set upon detecting an edge.

0 = Interrupt-on-Change disabled for the associated pin.

bit 3-0

Unimplemented: Read as ‘0’

Note 1: PIC16(L)F1459 only.

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 HS - Bit is set in hardware

bit 7-4 IOCBF<7:4>: Interrupt-on-Change PORTB 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.

bit 3-0

Unimplemented: Read as ‘0’

Note 1: PIC16(L)F1459 only.
