1. When RESET is released functionality is guaranteed down to VBOR0 min

2. This formula has to be applied on power supplies related to the IO structure described by the pin definition table.

3. For operation with voltage higher than Min (VDD, VDDA, VDD33USB) +0.3V, the internal Pull-up and Pull-Down resistors must

be disabled.

4. In low-power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax (see Section 8.10:

Thermal characteristics).
