Description
Reset. A 1-bit value to initialize the L3-bus registers with the default
settings by writing bit RST = 1. If bit RST = 0, there is no reset.
sampling frequency. Default 00; see
Voice ADC clock enable. A 1-bit value to enable the voice ADC clock. If
bit VCE = 1 (default), then the clock is enabled; if bit VCE = 0, then the
clock is disabled.
Voice ADC power control. A 1-bit value to reduce the power consumption
of the voice ADC. If bit VAP = 1, then the state is power-on; if bit VAP = 0
(default), then the state is power-off.
DSD mode selection. A 1-bit value to select the DSD mode. If
bit DSD = 1, then the DSD mode; if bit DSD = 0 (default), then the normal
mode.
System clock frequency. A 2-bit value to select the used external clock
frequency. 128f
bit DVD = 1. Default 00; see
Operating mode selection. A 2-bit value to select the operation mode of
the audio ADC and DAC. Default 00; see
Sampling frequency. A 2-bit value to select the sampling frequency of the
audio ADC and DAC in the WS mode. Default 01; see
ADC clock enable. A 1-bit value to enable the audio ADC clock. If
bit ACE = 1 (default), then the clock is enabled; if bit ACE = 0, then the
clock is disabled.
ADC power control. A 1-bit value to reduce the power consumption of the
audio ADC. If bit ADP = 1, then the state is power-on; if bit ADP = 0
(default), then the state is power-off.
DAC clock enable. A 1-bit value to enable the DAC clock. If bit DCE = 1
(default), then the clock is enabled; if bit DCE = 0, then the clock is
disabled.
DAC power control. A 1-bit value to reduce the power consumption of the
DAC. If bit DAP = 1, then the state is power-on; if bit DAP = 0 (default),
then the state is power-off.
