NOTE

Capacitive loading on Ports 0 and 2 may cause noise pulses to be superimposed on the VOLs of ALE and 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 1-to-0

exceed 08V 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
