5.2.4.10 BIST Register
This register is not supported in this device.
5.2.4.11 Base Address Registers
The Base Address registers are not supported in this device.
5.2.4.12 Primary Bus Number Register
The Primary Bus Number register is used to record the bus number of the PCI bus segment to which the
primary interface of the bridge is connected. Configuration software programs the value in this register. The
bridge uses this register to decode Type 1 configuration transactions on the secondary interface that must be
converted to Special Cycle transactions on the primary interface.
