CODEC Compatibility Class (RO)
This is a CODEC vendor specific field to define software compatibility for the
CODEC. Software reads this field together with the CODEC vendor ID (reg 7C-7Eh)
to determine vendor specific programming interface compatibility. Software can rely
on vendor specific register behavior to be compatible among vendor CODECs of
the same class.
00h - Field not implemented
01h-1Fh - Vendor specific compatibility class code
Equals Vendor ID2 (Reg 7Eh) bits D7 to D0
Revision ID: (RO)
This register specifies a device specific revision identifier. The value is chosen by
the vendor. Zero is an acceptable value. This field should be viewed as a vendor
defined extension to the CODEC ID. This number changes with new CODEC
stepping of the same CODEC ID.
Equals Major Rev bits (Reg 6Ch) bits D7 to D0.

PCI Sub System ID:
This field provides the PCI Sub System ID of the Audio or Modem Sub Assembly
(i.e., CNR Model, Motherboard SKU). This is NOT the CODEC vendor PCI ID, nor
the AC'97 Controller PCI ID. Information in this field must be available for AC'97
controller reads when CODEC Ready is asserted in AC-Link. If data is not
available, returns FFFFh.

PCI Sub System Vendor ID:
This field provides the PCI Sub System Vendor ID of the Audio or Modem Sub
Assembly Vendor (i.e., CNR Manufacturer, Motherboard Vendor). This is NOT the
CODEC vendor PCI Vendor ID, nor the AC'97 Controller PCI Vendor ID.
If data is not available, returns FFFFh.
