CODEC Compatibility Class (RO)
This is a CODEC vendor specific field to define software compatibility for
the CODEC. Software reads this field, together with 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.
