1. For operation with a voltage higher than VDDIOx + 0.3 V, the internal pull-up resistor must be disabled.

2. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax. See Section 7.7: Thermal characteristics.

3. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax (see Section 7.7:

Thermal characteristics).
