11.6 Interrupt-On-Change Registers
REGISTER 11-1: IOCAP: INTERRUPT-ON-CHANGE PORTA POSITIVE EDGE REGISTER
U-0 U-0 U-0 U-0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
— — — — IOCAP3 IOCAP2 IOCAP1 IOCAP0
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 Unimplemented: Read as ‘0’.
bit 3-0 IOCAP<3:0>: Interrupt-on-change PORTA 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.
(1)
0 = Interrupt-on-Change disabled for the associated pin.
Note 1: Interrupt-on-change also requires that the IOCIE bit of the INTCON register be set (Register 6-1).
REGISTER 11-2: IOCAN: INTERRUPT-ON-CHANGE PORTA NEGATIVE EDGE REGISTER
U-0 U-0 U-0 U-0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
— — — — IOCAN3 IOCAN2 IOCAN1 IOCAN0
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 Unimplemented: Read as ‘0’.
bit 3-0 IOCAN<3:0>: Interrupt-on-change PORTA 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.
(1)
0 = Interrupt-on-Change disabled for the associated pin.
Note 1: Interrupt-on-change also requires that the IOCIE bit of the INTCON register be set (Register 6-1).
