The user can use GPIOs to source or sink current. In this case, the user must ensure that these absolute

must always be connected to the external 3.3V or 5.0V supply.
I
must never be exceeded. This is implicitly insured if V
maximum is respected. If V

When several inputs are submitted to a current injection, the maximum
