DAC digital input select
DAC oversampling rate and power down control (only valid when
DAC_SRC = 00, S/PDIF receiver)
Selects the source for ZFLAG
Infinite zero detection circuit control and automute control
De-emphasis mode select
DEEMP[0] = 1, enable De-emphasis on DAC1
DEEMP[1] = 1, enable De-emphasis on DAC2
DEEMP[2] = 1, enable De-emphasis on DAC3
0 = De-emphasis controlled by DEEMP[2:0]
1 = De-emphasis enabled on all DACs
00 = DAC takes data from DIN1
01 = DAC takes data from DIN2
10 = DAC takes data from DIN3
0 = SFRM_CLK determines oversampling rate, DACs 2/3
