Note:
4. For open drain pins, high level output voltage is dependent on the external load.
5. All inputs that do not include internal pull-ups or pull-downs, must be externally driven for proper operation (See Table S on
page 44). If an input is not driven, it should be tied to power or ground, depending on the particular function. If an I/O pin is not
driven and programmed as an input, it should be tied to power or ground through its own resistor.
