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 S5920 from the external nvRAM at

power up.
