DESCRIPTION
15
DA_POL_INV
DAC polarity control. A 1-bit value to control the signal polarity of the
DAC output signal. When this bit is logic 0: DAC output not inverted.
When this bit is logic 1: DAC output inverted. Default value 0.
14
SEL_NS
Noise shaper order select. A 1-bit value to select between the
3rd-order and the 5th-order noise shaper. When this bit is logic 0: select
3rd-order noise shaper. When this bit is logic 1: select 5th-order noise
shaper. Default value 0.
13
MIX_POS
Mixer signal control. A 2-bit value to select the digital mixer settings
inside the interpolation filter. Default value 0. By default the mixer is off,
see Table 48.
12
MIX
11 to 8
default value 0000
7SILENCE
Silence mode. A 1-bit value to force the DAC output to silence. When
this bit is logic 0: no overruling. The setting of the FSDAC silence switch
depends on the status of the digital silence detector circuit and the
master_mute status. When this bit is logic 1: overruling. The FSDAC
silence switch is activated, independent of the status of the digital
silence detector circuit or the master_mute status. Default value 0.
6SDET_ON
Silence detector enable. A 1-bit value to enable the digital silence
detector. When this bit is logic 0: silence detection circuit disabled.
When this bit is logic 1: silence detection circuit enabled. Default
value 0.
5 and 4
SD_VALUE[1:0]
Silence detector settings. A 2-bit value to program the silence
detector, the number of ‘ZERO’ samples counted before the silence
detector signals whether there has been digital silence. Default
value 00, see Table 49.
3 and 2
default value 00
1 and 0
OS[1:0]
Oversampling input settings. A 2-bit value to select the oversampling
input mode. Default value 00, see Table 50.
