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

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.
