I have connected a DPRAM to EMIF module, the only problem I am facing is, the address and data lines are reverting back to its original state (with is LOGIC 1). But I need all the adress and data lines to maintain its previous state until I change my address or data. (all other control lines are working fine (like CS, W/R, etc))
please help me in this aspect.
thanks and regards,

Hi Satyanarayana Reddy,
maintain its previous state until I change my address or data.
It is not possible because after completion of write operation (CS deactivated), the address and data lines will become invalid by EMIF module.
So, we can't make them to hold on previous state.

Hi,
May i know, why it is so important for you to hold address and data lines?
If slave device requires some additional setup time or strobe time or Hold time in that case we can introduce some wait cycle by configuring below parameters
But i don't understand why you would like to hold them for until next operation, even if you are successfully able to do read and write operations.
