AC Inputs during testing are driven at V IHT (V DD -0.5V) for Logic "1" and
V ILT (0.45V) for a Logic "0". Measurement reference points for inputs and
outputs are at V HT (0.2V DD + 0.9) and V LT (0.2V DD - 0.1)

For timing purposes, a port pin is no longer floating when a 100 mV
change from load voltage occurs, and begins to float when a 100 mV
change from the loaded V OH /V OL level occurs. I OL /I OH = ± 20mA.
