PCI-to-PCI Bridge Standard Configuration Registers
This section provides a detailed description of the PCI-to-PCI bridge standard configuration registers.
Fields that have the same configuration Dword address are selectable by turning on (driving low) the
appropriate byte enable bits on P_CBE_b during the data phase. To select all fields of a configuration
address, drive all byte enable bits low.
All reserved fields and registers are read only and always return zero.
