programmed in the PEX_CONFIG_ADDR register. There is no configuration mechanism supported in EP
mode using the ATMU window. If the outbound ATMU window is configured to issue a configuration
transaction, all posted transactions hitting this window are ignored and all non-posted transactions get a
response with an error.
17.3.8
The first 64 bytes of the 256-byte PCI compatible configuration space consists of a predefined header that
every PCI device must support. The first 16 bytes of the predefined header are defined the same for all PCI
Express devices. These common registers are shown in
The remaining 48 bytes of the header may have differing layouts depending on the function of the device.
There are two header types applicable to PCI Express. Type 0 headers are typically used by endpoints;
Type 1 headers are used by root complexes and switches/bridges.
17.3.8.1
This section details the registers that are common to both type 0 and type 1 configuration headers.
