and port 1, 3, 4, 5, 6, and 9. 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 case (capacitive loading
> 100 pF), the noise pulse on ALE line may exceed 0.8 V. In such cases it may be desirable to qualify ALE
with a schmitt-trigger, or use an address latch with a schmitt-trigger strobe input.
