)
CODEC Compatibility Class (RO)
This is a CODEC vendor specific field to define software compatibility for
the CODEC. Software read 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
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 Vendor ID2(Reg 7Eh) bits D7 to D0
Equals Major Rev bits (Reg 6Ch) bits D7 to D0.
