Note:
AC testing inputs are driven at 3.5 V for a logic “1” and 0.45 V for a logic
“0”. Timing measurements are made at 2.0 V for a logic “1” and 0.8 V for
a logic “0”.

Points
V_OH – 0.15 V
V_OL + 0.15 V
Note:
For timing purposes, a port pin is no longer floating when a 150 mV change from load
voltage occurs and begins to float when a 150 mV change from the loading V_OH/V_OL
level occurs with I_OL/I_OH ≤15 mA.
