Hi,
Does anyone know the SOC/integration/pin-connection expert?
My customer would like to use one WAIT pin for multiple CS(Customer would like to use both Asynchronous I/F and Synchronous I/F each CS(Chip Select) with one WAIT pin). Can TI guarantee the GPMC of AM3874 with this use?
And I got answer from TI engineer as the above.
> This is possible , but not advised. GPMC has two wait pins, Is the customer using all of them? Can you advice him to use another Wait pin that is not used?
My customer said to me. When synchronous I/F using, WAIT1 must select the clock. So customer only use WAIT0. This means that WAIT pin is only one for CS0-CS4.
Then TI engineer said that this using (one WAIT pin for multiple CS) must be confirmed to SOC/intergration/pin-connection expert.
Please confirm this using is possible or not to the expert. I don't know the SOC/integratio/pin-connection expert person.
Best regards,
Michi
