S5320 – PCI Match Maker: PCI Configuration Registers
Data Sheet
Subsystem ID Register (SID)
This register is used to further identify the add-in 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 ID is vendor-specific. It is
loaded by the S5320 from the external nvRAM at
power up.
