4. Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the V

and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins make 1 to 0
transitions during bus operation. In the worst cases (capacitive loading 100 pF), the noise pulse on the ALE line may exceed
0.45V with maxi V
and 5V.
