7to4
default value 0000
3SEL_LNA
Line input select. A 1-bit value to set the multiplexer in the analog front-end to select
between the LNA or the enable-in input for the left ADC. When this bit is logic 0: select
line input. When this bit is logic 1: select LNA for the left ADC. Default value 0.
2SEL_MIC
Microphone input select. A 1-bit value to set the multiplexer at the ADC right
channel output (on bit-stream level) which selects either the right channel data or the
left channel data. In case only the microphone input is used, the microphone signal
can be applied to the decimator for both left and right. When this bit is logic 0: select
right channel ADC. When this bit is logic 1: select left channel ADC (for instance for
microphone input). Default value 0.
1SKIP_DCFIL
DC filter bypass. A 1-bit value set to skip the DC filter which is just before the
decimator. This DC filter is there to compensate for the DC offset added in the ADC (to
remove idle tones from the audio band). This DC signal added (the DC dither) must
not be amplified in order to prevent clipping. Therefore this DC offset is removed first.
When this bit is logic 0: DC filter enabled. When this bit is logic 1: DC filter bypassed.
Default value 1.
0
EN_DCFIL
DC filter enable. A 1-bit value set to enable the DC filter which is at the output of the
decimator (running at 1fs). When this bit is logic 0: DC filter disabled. When this bit is
logic 1: DC filter enabled. Default value 0.
