Description
ADC DC-filter. A 1-bit value to enable the digital DC-filter of the ADC. If
bit DC = 1 (default), then the DC-filtering is active; if bit DC = 0, then there
is no DC-filtering.
Polarity ADC 2 control. A 1-bit value to control the ADC 2 polarity. If
bit PAB = 1, then the polarity is inverted; if bit PAB = 0 (default), then the
polarity is non-inverted.
Polarity ADC 1 control. A 1-bit value to control the ADC 1 polarity. If
bit PAA = 1, then the polarity is inverted; if bit PAA = 0 (default), then the
polarity is non-inverted.
Mute ADC 2. A 1-bit value to enable the digital mute of ADC 2. If
bit MTB = 1, then ADC 2 is soft muted; if bit MTB = 0 (default), then ADC 2
is not muted.
Mute ADC 1. A 1-bit value to enable the digital mute of ADC 1. If
bit MTA = 1, then ADC 1 is soft muted; if bit MTA = 0 (default), then ADC 1
is not muted.
ADC output data interface format. A 3-bit value to select the used data
format to the I
DAC gain switch. A 1-bit value to select the DAC gain. If bit DAG = 1, then
the gain is 6 dB; if bit DAG = 0 (default), then the gain is 0 dB.
Filter selection. A 1-bit value to select the interpolation filter
characteristics. If bit FIL = 1, then slow roll-off; if bit FIL = 0 (default), then
sharp roll-off.
192 kHz sampling mode selection. A 1-bit value to select the
oversampling rate of the noise shaper. The 64f
and 176.4 kHz sampling frequencies. If 7-bit DVD = 1, then 64f
selected (192 kHz sampling mode); if bit DVD = 0 (default), then 128f
is selected.
Data interface selection. A 2-bit value to select the data interface
connection. Default 00; see
DAC input data interface format. A 3-bit value to select the used data
format to the I
