Buffer Types
Sink and source capabilities are dependant on the VDDVARIO voltage. Refer to
7.6, "DC Electrical Specifications"
When operating at reduced VDDVARIO voltage levels (less than 3.0V), do not rely on
internal pull-up and pull-down resistors to determine signal state. Refer to
"External Pull-Up/Pull-Down Resistors"
2.1, "Pin List"
