Telecom codec sample rate divisor.
Valid values are between [0010000] (=16) and [1111111] (=127)
If ‘1’, the loopback mode of within the telecom codec is enabled.
If ‘1’, the voice band filter in the telecom input path is enabled
The bit returns the actual telecom clip detection status.
A ‘0’ to ‘1’ transition bit clears the telecom clip detection status
If ‘1’, the telecom input attenuation (6dB) is enabled.
If ‘1’, the sidetone suppression circuit is activated
If ‘1’, the telecom output is muted
If ‘1’, the telecom input path is activated
If ‘1’, the telecom output path is activated
Audio codec sample rate divisor.
Valid values lie between [00000110] (=6) and [1111111] (=127).
Audio input gain setting.
Values range from [00000] (no gain) to [11111] (46.5dB gain)
Audio output attenuation setting.
Values range from [00000] (no attenuation) to [11111] (69dB attenuation).
If ‘1’, the audio clip detection circuitry is activated
If ‘1’, the loopback mode in the audio codec is activated.
If ‘1’, the audio output is muted
If ‘1’, the audio codec input path is activated.
If ‘1’, the audio codec output path is activated.
