8.2. PCI Express* Configuration Space

In addition to accessing the Endpoint's configuration space registers by sending Configuration Read/Write TLPs, the AXI-Lite CSR interface also provides read/write access to these registers.

The PCIe* Configuration Space Registers table describes the registers for each PF. To calculate the address for a particular register in a particular PF, add the offset for that PF from the Configuration Space Offsets table to the byte address for that register as given in the PCIe* Configuration Space Registers table.
