AC Testing Input/Output

Waveforms

Figure 8. AC Testing Input/Output Waveforms

AC inputs during testing are driven at VCC - 0.5 for a logic “1” and 0.45V for a logic “0”.

Timing measurement are made at VIH min for a logic “1” and VIL max for a logic “0”.

Figure 9. Float Waveforms

For timing purposes as port pin is no longer float ing when a 100 mV change from load

voltage occurs and begins to float when a 100 mV change from the loaded V

OH/VOL level

occurs. I

OL/IOH ≥ ± 20mA.

Clock Waveforms

Valid in normal clock mode. In X2 mode XTAL2 signal must be changed to XTAL2

divided by two.
