The input signals in AC test mode are either V
OH
(logic "1") or V
OL
(logic "0") input signals
where logic "1" corresponds to a CPU output signal waveform measuring point in excess of
V
IH
, and logic "0" to a point below V
IL
.

The port 0 floating interval is measured from the time the port 0 pin voltage drops below V
IH
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 V
IL
after connecting to a 400
mA
source when switching
to floating status from a "0" output.
