Data Mode Data and Control Registers
Data Byte 1, Left Audio Data—Most Significant 8 Bits
In 16-bit linear PCM mode, this byte contains the upper eight bits of the left audio data sample. In the 8-bit companded and linear
modes, this byte contains the left audio data sample. In mono mode, only the left audio data is used. MSB first format is used in all
modes, and twos-complement coding is used in 16-bit linear PCM mode.
Data Byte 2, Left Audio Data—Least Significant 8 Bits
In 16-bit linear PCM mode, this byte contains the lower eight bits of the left audio data sample. In the 8-bit companded and linear
modes, this byte is ignored on input, zeroed on output. In mono mode, only the left audio data is used. MSB first format is used in
all modes, and twos-complement coding is used in 16-bit linear PCM mode.
Data Byte 3, Right Audio Data—Most Significant 8 Bits
In 16-bit linear PCM mode, this byte contains the upper eight bits of the right audio data sample. In the 8-bit companded and linear
modes, this byte contains the right audio data sample. In mono mode, this byte is ignored on input, zeroed on output. MSB first
format is used in all modes, and twos complement coding is used in 16-bit linear PCM mode.
Data Byte 4, Right Audio Data—Least Significant 8 Bits
In 16-bit linear PCM mode, this byte contains the lower eight bits of the right audio data sample. In the 8-bit companded and linear
modes, this byte is not used. In mono mode, this byte is ignored on input, zeroed on output. MSB first format is used in all modes,
and twos-complement coding is used in 16-bit linear PCM mode.

Output Line 1 Analog Mute:
Output Line 0 Analog Mute:
Output attenuation setting for the left DAC channel; “0” represents no attenuation. Step size is 1.5 dB; “62” represents
93 dB of attenuation. Attenuation = 1.5 dB × LO, except for LO = “63,” which represents full digital mute.
