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 processor is not in debug mode. Thus the internal pull-up corresponding

5. TDO pin is set in input mode when the Cortex-M4 processor 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
