Description
SU Vendor ID - This is a 16-bit value assigned to Intel. This register, combined with the DID, uniquely
identify the PCI device. Access type is Read/Write to allow the GD31244 controller to configure the
register as a different vendor ID to simulate the interface of a standard mechanism currently used by
existing application software.
