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.
Then, it may be desirable to qualify ALE with a Schmitttrigger, or use an address latch
with a Schmitttrigger strobe input.
