19.4.5. External Clock Drive Waveforms
19.4.6. AC Testing Input/Output Waveforms
AC inputs during testing are driven at V
are made at V
19.4.7. Float Waveforms
For timing purposes as 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
