NOTES

Ports 1 2 and 3 The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins

change from 1 to 0 In applications where capacitance loading exceeds 100 pF the noise pulses on these signals may

exceed 08V It may be desirable to qualify ALE or other signals with a Schmitt Trigger or CMOS-level input logic
