DAC left and DAC right volume do not update until a
1 is written to either DAC_VU register bit.
0000_0000 = Digital mute
0000_0001 = -71.625dB
0000_0010 = -71.25dB
… (0.375dB steps)
1100_000 = 0dB
Adds left and right channel and halves the
resulting output to create a mono output
Mode Select
1 = USB mode (272 * Fs)
0 = Normal mode (256 * Fs)
DAC De-emphasis filter control
00 = No de-emphasis
01 = 32kHz sample rate
10 = 44.1kHz sample rate
11 = 48kHz sample rate
DAC_SDMCLK_RATE allows the DAC SDM to
be run at a speed higher than 64*fs. This is used
for low sample rate modes to allow the SDM to
run fast enough to shape the noise so that none
of it appears in the audio band. On the previous
version, at 8k sample rate you could hear some
high frequency noise when playing back through
a decent system.
DAC data left channel polarity
0 = Normal
1 = Inverted
DAC data right channel polarity
0 = Normal
1 = Inverted
