7.2. PCI Express* Configuration Space
I additio to accessig the Edpoit's cofiguatio space egistes by sedig Cofiguatio Read/Wite TLPs, the AXI-Lite CSR iteface also povides ead/wite access to these egistes.
The PCIe* Cofiguatio Space Registes table descibes the egistes fo each PF. To calculate the addess fo a paticula egiste i a paticula PF, add the offset fo that PF fom the Cofiguatio Space Offsets table to the byte addess fo that egiste as give i the PCIe* Cofiguatio Space Registes table.
