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 7-6 Unimplemented: Read as ‘0’
bit 5-0 IOCAP<5:0>: 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.
0 = Interrupt-on-Change disabled for the associated pin.
REGISTER 13-2: IOCAN: INTERRUPT-ON-CHANGE PORTA NEGATIVE EDGE REGISTER

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.

bit 5-0 IOCAF<5:0>: Interrupt-on-Change PORTA Flag bits
1 = An enabled change was detected on the associated pin.
Set when IOCAPx = 1 and a rising edge was detected on RAx, or when IOCANx = 1 and a falling edge
was detected on RAx.
0 = No change was detected, or the user cleared the detected change.
