S5320 – PCI Match Maker: PCI Configuration Registers
Data Sheet
Subsystem Vendor Identification Register (SVID)
This register is used to uniquely identify the user board
or subsystem. It provides a mechanism for add-in card
vendors to distinguish devices with the same Vendor
ID and Device ID. Implementation of this register is
mandatory for 2.2 compliance and an all-zero value
indicates that the device does not support subsystem
identification. Subsystem Vendor IDs may be obtained
directly from the PCI SIG by the user and it is loaded
by the S5320 from the external nvRAM at power up.
