IOCAN<7:4>: Interrupt-on-Change PORTB Negative Edge Enable bits
1 = Interrupt-on-change enabled on the pin for a negative going edge. Associated Status bit and interrupt
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.
