Note: AC inputs during testing are driven at VCC–0.5V for a logic '1,' and 0.45V for a logic '0.'

Timing measurements are made at VIH(min) for a logic '1,' and VIL(max) for a logic '0'

Note: For timing purposes, a Port pin is considered to be no longer floating when a 100mV change from load voltage occurs, and begins to

float when a 100mV change from the loaded VOH or VOL level occurs
