Agilex 7 M EMIF User-Controlled Refresh

The Agilex 7 M EMIF user guide (UG 772538, version 2025.03.31) lists user-controlled refresh timing as a feature, but does not describe how to use that feature. I need to use this feature for my application, is it possible for documentation to be provided for this feature?

This is from table 18 which describes the controller's features:

"User-controlled refresh timing—optionally, you can control when refreshes occur and this allows you to prevent important read or write operations from clashing with the refresh lock-out time."

I assume this would be controlled using the mailbox interface from section 12, but there are no commands listed for controlling refresh timing.

Hi


Currently no option available to enable the User-Controlled Refresh feature in the EMIF IP.

I still waiting for confirmation if there is any mailbox command that can be used for this feature.

I will let you know once I get the details.

Hi Adzim, thank you for looking into it.

If it turns out this feature is planned but not yet released, please let me know if there is a way to get early access to documentation so that I can prepare my design ahead of time.

Hi


I have confirmed with engineering that this feature is not supported in Agilex 7 M-series device.

The UG will be updated with the correct information in future.

Sorry for any inconvenience cause.


Regards,

Adzim
