Comments
Reset State:
- USB Mode
- Internal Pull-down(3)
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.
