PCI Express* extends the configuration space to 4096 bytes per-device/function, as compared to 256 bytes allowed by the conventional PCI specification. PCI Express* configuration space is divided into a PCI-compatible region (that consists of the first 256 bytes of a logical device's configuration space) and an extended PCI Express* region (that consists of the remaining configuration space). The PCI-compatible region can be accessed using either the mechanisms defined in the PCI specification or using the enhanced PCI Express* configuration access mechanism described in the PCI Express* Enhanced Configuration Mechanism section.

The PCI Express* Host Bridge is required to translate the memory-mapped PCI Express* configuration space accesses from the host processor to PCI Express* configuration cycles. To maintain compatibility with PCI configuration addressing mechanisms, it is recommended that system software access the enhanced configuration space using 32-bit operations (32-bit aligned) only. See the PCI Express Base Specification for details of both the PCI-compatible and PCI Express* Enhanced configuration mechanisms and transaction rules.

PCI Express* Port

The PCI Express* interface on the processor is a single, 16-lane (x16) port that can also be configured at narrower widths. The PCI Express* port is being designed to be compliant with the PCI Express Base Specification, Revision 3.0.
