Notes:

1. See “Typical Powering Schematics” section of this datasheet for restrictions on voltage range of Analog Cells.

2. Schmitt Triggers can be disabled through PIO registers.

3. 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.
