4.4 Pin Multiplexing Tables
Multiple usage pins are used to conserve pin consumption for different features. The devices can be
used in many different applications but each application will not utilize all the on chip features. As a
result, some of the features share the same pin. Most of the multiple usage pins can be used as a
GPIO pin as well.
