In this mechanism the 4KB of config space will be mapped into the memory called memory mapped config, this mechanism will provide 12 bits for offset of the config registers you want to access. Now lets talk about the ECAM (Enhanced configuration access mechanism) which is used in PCI Express to access the config space of a PCIe device. But in case of PCI Express devices only first 256 bytes of config space can be accessed through this mechanism, This mechanism will not support to access remaining PCIe config space!!!! It will perfectly makes sense for PCI device since entire 256 bytes config space can be accessed in 1 bytes offset (256 entries). Now if you look at the address format of PCI config space mechanism you would see that 1 Byte has been given to provide the offset of the register you want to access in PCI config space. The PCI provides 256 Bytes of config space, But is has been increased to 4KB for PCI Express devices. This mechanism of accessing configuration space registers is called Legacy/PCI configuration access mechanism. BIOS writes BUS-DEVICE-FUNCION-CONFIG_REGISTER_OFFSET into 0xCF8 to access the particular register in config space, and the value of the register will be fetched from 0xCFC(config data port), These operations are done by invoking OUT and IN instruction. Intel architecture provides two port address 0xCFC(config data port) & 0xCF8(config address port) to access the config space of the PCI device. BIOS will have to first access the config space of the end point device inorder to set up the MMIO or IO address range for it (If device request for the MMIO or IO addresses via BAR registers to access its internal memory).
