and ports1, 3, 4, and 5. 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.
