Figure 42. Float waveform
For timing purposes a port pin is no longer floating when VLOAD changes of ±100mV.
It begins to float when a 100mV change from the loaded VOH/VOL level occurs (IOH/IOL = 20mA).
AC inputs during testing are driven at 2.4V for a logic ‘1’ and 0.4V for a logic ‘0’.
Timing measurements are made at VIH Min. for a logic ‘1’ and VIL max for a logic ‘0’.
