FOOTNOTE:
(1) _{The input test for the 3.3 V environment is done with 0.1*VDD_io of overdrive. Timing parameters must be met with no more overdrive}
than this. Production testing may use different voltage values, but must correlate results back to these parameters.
(2) _{Vmax specifies the maximum peak-to-peak voltage waveform allowed for measuring input timing. Production testing may use different}
voltage values, but must correlate results back to these parameters.
