I am using externel memory eprom for data storage , we couldnt fetch the data from the externel memory. So it seems the problem is with the speed of executon. So please help me configure WAIT STATES.
... you provide a link to the datasheet (at the manufacturers website, not some datasheet collection site) for both your uC and your memory. Also, you need to post your clock speed. I take that you do have a low address latch (which chip).
