PCI Express Interface Controller
17.3.8.3.1
Base address register 0 at offset 0x10 is a special fixed 1-Mbyte window that is used for inbound
configuration accesses. This window is called the PCI Express configuration and status register base
address register (PEXCSRBAR). Note that PEXCSRBAR cannot be updated through the inbound ATMU
registers. The PEXCSRBAR is shown in
Table 17-46
