54.3.3. Unsupported Feature
The message data entry Avalon® -MM Agent represents the system-specified address for MSI function. The offset seen by MSI function should be similar to the offset seen by the host processors. As this Avalon® -MM Agent interface is accessible (write and read) by both the host processor and the PCIe RP HIP, any read transaction to the offset address (system-specified address) is considered to have the message data entry consumed. Observing this limitation, only host host, which is expected to serve the MSI should read from the Avalon® -MM Agent interface. A read from the PCIe RP_Master to the Avalon® -MM Agent is prohibited.
