Suggestion for input pin options, both analog and digital,
offer a setting that biases the input to Vdd/2. This is to
facilitate AC coupling of either digital or analog signals.
Of course this has impact on power, eg under certain situations,
pin left floating, input structure would draw current, both the divider
and the N-P CMOS input transistors.
