1. With a first-generation codec, this parameter is set by external components. Any complex impedance R
2. This parameter is not tested in production. It is guaranteed by design and device characterization.
3. Use this gain option with a first-generation or third-generation codec.
4. Use this gain option with an Agere third-generation codec.
