maximum must always be respected. Refer to Nominal Ratings for the maximum allowed injected current
values.
(3) This formula has to be applied only on the power supplies related to the IO structure described in the pin
definition table.
(4) To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.
(5) Include VREF- pin.
