Function
Optional per AC ‘97 specifications, should be implemented as read/write on AD1986A.
This field provides the PCI subsystem vendor ID of the audio or modem subassembly vendor (that is, CNR manufacturer,
motherboard vendor). This is not the codec vendor PCI vendor ID or the AC ’97 controller PCI vendor ID. If data is not
available it returns 0xFFFF.
Function
Optional per AC ‘97 specifications, should be implemented as read/write on the AD1986A. This field provides the PCI
subsystem ID of the audio or modem subassembly (that is, CNR model, motherboard SKU). This is not the codec vendor PCI
ID or the AC ’97 controller PCI ID. Information in this field must be available, because the AC ’97 controller reads when the
codec ready is asserted in the AC link. If data is not available, it should return 0xFFFF.
