AC testing inputs are driven at 2.4 V for a logic 1 and 0.45 V for a logic 0.
Timing measurements are taken at 2.0 V for a logic 1 and 0.8 V for a logic 0, see Fig.30a.
The float state is defined as the point at which a Port 0 pin sinks 3.2 mA or sources 400 µA at
the voltage test levels, see Fig.30b.
