Ports 1 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these
pins make HIGH-to-LOW transitions during bus operations. In the worst cases (capacitive loading > 100pF), the
noise pulse on the ALE pin 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. I
