PCI Express Interface Controller
The fields of the PCI Express configuration address register are described in
Both root complex (RC) and endpoint (EP) configuration headers contain 4096 bytes of address space. To
access a register within the header, both the extended register number and the register number fields are
concatenated to form the 4-byte aligned address of the register. That is, the register address is extended
register number || register number || 0b00.
18.3.2.2
The PCI Express configuration data register, show in
configuration access. Note that accesses of 1, 2, or 4 bytes to the PCI Express configuration data register
are allowed. Also note that accesses to the little-endian PCI Express configuration space must be properly
formatted. See
