Notes: 1. Do not change the initial value (input-buffer disabled) of PnICR, where n corresponds to
an unused pin.
2. When changing the pin function from its initial state, use a pull-up or pull-down resistor
as needed.
Mode 4
•
Since this is the address output in its initial state, leave the pin
unconnected.

Mode 5
Since this is a general-purpose input
port in its initial state, connect each
