Description
Input channel selection. A 2-bit value to select the input channels. As
the controlled channels are paired off, this 2-bit value must be written
to each odd channel register. Default 00. See
De-emphasis setting. A 3-bit value to enable the digital de-emphasis
filter. Default 000. See
Polarity DAC control. Bit PD controls the DAC polarity.
Muting. Bit MT enables the digital mute. All the DAC outputs are
muted at start-up. It is necessary to explicitly switch off for the audio
output by means of bit MT.
Quick mute. Bit QM sets the quick mute mode.
Interpolator volume control. An 8-bit value to program the volume
attenuation of each channel. The range is from 0 dB to 53 dB in steps
of 0.25 dB, from 53 dB to 80 dB in steps of 3 dB and
Default 0000 0000. See
1 = polarity is inverted
0 = polarity is not-inverted (default)
1 = muting (start-up)
0 = no muting (default)
1 = quick mute mode
0 = soft mute mode (default)
