Thank you for response. Later yesterday I saw other @Community member​ posts and your reactions. I think that waiting for timeout and then calling abort will be in result slower than using (1-1-1) for polling (which is working fine)

Hello,I am having an issue with autopolling too. I tried a lot of combinations of modes (1/4 Instruction lines, 1/4 Address lines, 1/4 Data lines). For me it seems there is a problem at least with (4-4-4) mode with autopolling. It looks it works fine...
