Function
These bits specify a device specific revision identifier. The vendor chooses this value. 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. This number will increment with each stepping/rev. of the
codec chip.
The AD1986A will return 0x00 from this register. This is a codec vendor specific field to define software
compatibility for the codec. Software reads this field together with codec vendor ID (Register 0x7C–0x7E)
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.
