- Make sure the MSI feature is disabled in the IP Parameter Editor GUI.
- Check the Enable PCI Express Extended Space (CEB) option and specify the CEB REQ to ACK latency (in Clock Cycles).
- Set the CEB PF External Standard Capability Pointer Address (DW address in Hex) value to 0x14 and leave CEB PF External Extended Capability Pointer Address (DW address in Hex) in the default setting, 0x0.

The figure below shows the capability link list for this implementation:
