The Output Buffer is disabled.
The Schmitt Trigger Input is de-activated providing zero consumption for every analog
value of the I/O pin. The output of the Schmitt Trigger is forced to a constant value (0).
The weak pull-up and pull-down resistors are disabled.
Read access to the Input Data Register gets the value “0”.
