PCI bus specifies the bus transaction that accesses the configuration space, which is called the configuration read/write transaction. Unlike the storage access transactions that use the storage address for access, the idnumber is used for addressing access to the PCI configuration space. The ID of a PCI device consists of the bus number, device number, and funct
