Input/output signal VOH VIH TEST POINT VOL VIL VIL VOL VIH MSM85C154HVS VOH * The input signals in AC test mode are either VOH (logic "1") or VOL (logic "0") input signals where logic "1" corresponds to a CPU output signal waveform measuring point in excess of VIH, and logic "0" to a point below VIL. 2. Floating VOH Floating VIH VIL VIH VIL VOH VOL VOL * The port 0 floating interval is measured from the time the port 0 pin voltage drops below VIH after sinking to GND at 2.4 mA when switching to floating status from a "1" output, and from the time the port 0 pin voltage exceeds VIL after connecting to a 400 mA source when switching to floating status from a "0" output.
