14.6 Register Definitions: Interrupt-on-Change Control
REGISTER 14-1: IOCxP: INTERRUPT-ON-CHANGE POSITIVE EDGE REGISTER
R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
IOCxP7 IOCxP6 IOCxP5 IOCxP4 IOCxP3 IOCxP2 IOCxP1 IOCxP0
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
IOCxP<7:0>: Interrupt-on-Change Positive Edge Enable bits
(1)
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.
Note 1: For IOCEP register, bit 3 (IOCEP3) is the only implemented bit in the register.
REGISTER 14-2: IOCxN: INTERRUPT-ON-CHANGE NEGATIVE EDGE REGISTER
R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
IOCxN7 IOCxN6 IOCxN5 IOCxN4 IOCxN3 IOCxN2 IOCxN1 IOCxN0
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
IOCxN<7:0>: Interrupt-on-Change Negative Edge Enable bits
(1)
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.
Note 1: For IOCEN register, bit 3 (IOCEN3) is the only implemented bit in the register.
