SEL_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.
2
SEL_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.
1
SKIP_DCFIL
DC lter bypass. A 1-bit value set to skip the DC lter which is just before the
decimator. This DC lter 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 amplied in order to prevent clipping. Therefore this DC offset is removed rst.
When this bit is logic 0: DC lter enabled. When this bit is logic 1: DC lter bypassed.
Default value 1.
0
EN_DCFIL
DC lter enable. A 1-bit value set to enable the DC lter which is at the output of the
decimator (running at 1fs). When this bit is logic 0: DC lter disabled. When this bit is
logic 1: DC lter enabled. Default value 0.
