UPD720201 PCI-E compatibility


We are looking forward to integrate the UPD720201K8-711-BAC-A with a Compute Module 4 (CM4) from the Raspberry Foundation. The CM4 has a single PCI-E 2.0 1x lane with the following limitations:

- No support for MSI-X

- No support for 64-bit PCI-E bus access

Do these limitations pose a problem for the UPD720201K8? In other words, can the UPD720201K8 work correctly with only 32-bit bus access and without MSI-X?

Thank you
