Local properties
^^^^^^^^^^^^^^^^

.. _CIM-PCIBridge-MemoryBase:

``uint16`` **MemoryBase**

    Base address of the memory supported by the bus. The upper 12 bits of this property specify the address bits, AD[31::20], of a 32-bit memory address. Each of the remaining 20 bits of the address are assumed to be 0.

    
.. _CIM-PCIBridge-IOLimit:

``uint8`` **IOLimit**

    End address of the I/O addresses supported by the bus. The upper 4 bits of this property specify the address bits, AD[15::12], of the I/O address. Each of the remaining 12 bits of the I/O address are assumed to be 1.

    
.. _CIM-PCIBridge-IOBase:

``uint8`` **IOBase**

    Base address of I/O addresses supported by the bus. The upper 4 bits of this property specify the address bits, AD[15::12], of the I/O address. Each of the remaining 12 bits of the I/O address are assumed to be 0.

    
.. _CIM-PCIBridge-IOBaseUpper16:

``uint16`` **IOBaseUpper16**

    Upper 16 bits of the supported I/O base address when 32-bit I/O addressing is used. The lower 16 bits are assumed to be 0.

    
.. _CIM-PCIBridge-PrefetchLimitUpper32:

``uint32`` **PrefetchLimitUpper32**

    Upper 32 bits of the supported prefetch end address when 64-bit addressing is used. The lower 32 bits are each assumed to be 1.

    
.. _CIM-PCIBridge-BridgeType:

``uint16`` **BridgeType**

    The type of bridge. Except for "Host" (value=0) and "PCIe-to-PCI" (value=10), the type of bridge is PCI-to-<value>. For type "Host", the device is a Host-to-PCI bridge. For type "PCIe-to-PCI", the device is a PCI Express-to-PCI bridge.

.. _CIM-PCIBridge-PrimaryBusNumber:

``uint8`` **PrimaryBusNumber**

    The number of the PCI bus segment to which the primary interface of the bridge is connected.

    
.. _CIM-PCIBridge-IOLimitUpper16:

``uint16`` **IOLimitUpper16**

    Upper 16 bits of the supported I/O end address when 32-bit I/O addressing is used. The lower 16 bits are each assumed to be 1.

    
.. _CIM-PCIBridge-SecondaryLatencyTimer:

``uint8`` **SecondaryLatencyTimer**

    The timeslice for the secondary interface when the bridge is acting as an initiator. A 0 value indicates no requirement.

    
.. _CIM-PCIBridge-PrefetchMemoryLimit:
