Intel Xeon® Processor X3430 (8M Cache, 2.40 GHz) BX80605X3430 User Manual

180

Intel® Xeon® Processor 3400 Series Datasheet, Volume 2

and resides at DID of 2CAAh. Device 5, Function 3 contains the thermal control 
registers for Integrated Memory Controller Channel 1 and resides at DID of 2CABh.

Each component in the processor is uniquely identified by a PCI bus address consisting 
of Bus Number, Device Number and Function Number. Device configuration is based on 
the PCI Type 0 configuration conventions. All processor registers appear on the PCI bus 
assigned for the processor socket. Bus number is derived by the max bus range setting 
and processor socket number.
