Unimplemented: Read as ‘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
0 = Interrupt-on-Change disabled for the associated pin.
Unimplemented: Read as ‘0’
IOCAN<5:0>: 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
0 = Interrupt-on-Change disabled for the associated pin.
Unimplemented: Read as ‘0’
IOCAF<5:0>: Interrupt-on-Change PORTA Flag bits
1 = An enabled change was detected on the associated pin.
0 = No change was detected, or the user cleared the detected change.
Set when IOCAPx = 1 and a rising edge was detected on RAx, or when IOCANx = 1 and a falling edge
was detected on RAx.
flag will be set upon detecting an edge.
flag will be set upon detecting an edge.
