AMIX: Analog Mixing Control for External Analog Signal, AIN
Default Value: 0
AMIX = 0
AMIX = 1
Disabled (not mixed)
Enabled (mixing to the DAC output)
AMIX bit allows the user to mix analog input (AIN) with line outputs (V
OUT
L/V
OUT
R) internally.
DEM: 44.1-kHz De-Emphasis Control
Default Value: 0
DEM = 0
DEM = 1
Disabled
Enabled
The DEM bit enables or disables the digital de-emphasis filter for 44.1-kHz sampling rate.
FMT[2:0]: Audio Interface Data Format
Default Value: 000
The FMT[2:0] bits select the data format for the serial audio interface. The following table shows the available
format options.

ZCAT: Zero Cross Attenuation
Default Value: 0
ZCAT = 0
ZCAT = 1
Normal attenuation (default)
Zero cross attenuation
This bit enables to change signal level on zero crossing during attenuation control or muting. If the signal does not
cross BPZ beyond 512/f
S
(11.6 ms at 44.1-kHz sampling rate), the signal level is changed similar to normal
attenuation control. This function is independently monitored for each channel; moreover, change of signal level
is alternated between both channels. Figure 28 shows an example of zero cross attenuation.
