5.2. Type 0 Configuration Space Registers
Figure 18. Type 0 Configuration Space Registers - Byte Address Offsets and LayoutEndpoints store configuration data in the Type 0 Configuration Space. The Correspondence between Configuration Space Registers and the PCIe Specification lists the appropriate section of the PCI Express Base Specification that describes these registers.
