Fig.25 AC testing input, output waveform (a) and float waveform (b).
AC testing inputs are driven at 2.4 V for a HIGH and 0.45 V for a LOW.
Timing measurements are taken at 2.0 V for a HIGH and 0.8 V for a LOW, see Fig.25 (a).
The float state is defined as the point at which a Port 0 pin sinks 3.2 mA or sources 400
μ
