Note 2.1 Sink and source capabilities are dependant on the VDDVARIO voltage. Refer to Section
7.6, "DC Electrical Specifications" for additional information.
Note 2.2
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 Section 2.2,
"External Pull-Up/Pull-Down Resistors" and the individual signal descriptions in Section
2.1, "Pin List" for more information.
