2.3.5. Supported Memory Protocols Among Device Families

The following table describes what memory protocols are supported on the HPS EMIF across the different devices.

Warning: Mismatching the HPS protocol and parameters with the HPS-EMIF protocol and parameters is not supported. For example, configuring the HPS to be DDR4 1x16 and configuring the HPS-EMIF to be DDR4 1x32 is not supported.
