Fig 35. AC testing input/output test waveform.
Fig 36. Float waveform.
Fig 37. Test load example.
AC inputs during testing are driven at V
points for inputs and outputs are at V
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
