I am using Proteus 7.6 to simulate a 68HC11E9 chip with external RAM chip connected. I am trying to read and write to the external memory but without use. I put the MODA and MODB pins so that the processor in the expanded mode.

I tried to look at the examples provided by Labcenter and I think the external memory modules are not working either in these examples.

I hope you have the time to look at my own design and point to me any stupid mistake that I did.

Thanks in advance.
