7.2.2. User-Controlled Refresh

The user-controlled refresh feature allows you to take control of the refresh process that the controller normally performs automatically. You can control when refresh requests occur, and, if there are multiple memory devices, you control which bank receives the refresh signal.

When you enable this feature, you disable auto-refresh, and assume responsibility for maintaining the necessary average periodic refresh rate. You can enable user-controlled refresh in the Controller Settings section of the General Settings tab of the parameter editor.
