MSI Requests not Supported in IP Compiler for PCI Express in Completer Only Mode

Description

When you configure the IP Compiler for PCI Express in Completer Only mode, if an MSI is sent by asserting an interrupt, any subsequent reads returns all zeros.

This issue affects variants that use the Avalon-MM interface and select Completer Only mode on the Avalon Configuration tab.

Resolution

To avoid this issue, configure your IP Compiler for PCI Express in Requester/Completer mode.

This issue will be not fixed in a future version of the PCI Express MegaCore function.
