Note:

1. Schmitt Triggers can be disabled through PIO registers.

2. Some PIO lines are shared with System I/Os.

3. Refer to USB Section of the product Electrical Characteristics for information on Pull-down value in USB Mode.

4. See “Typical Powering Schematics” Section for restrictions on voltage range of Analog Cells.

5. TDO pin is set in input mode when the Cortex-M4 Core is not in debug mode. Thus the internal pull-up corresponding 

to this PIO line must be enabled to avoid current consumption due to floating input
