test points
Fig.31 AC testing input, output waveform (a) and float waveform (b).
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 logic 0 see (a). The float state is defined as the point
at which a Port 0 pin sinks 3.2 mA or sources 400
A at the voltage test levels see (b).
