Description
Reset. Bit RST initializes the L3-bus registers with the default settings.
Voice ADC sampling frequency. A 2-bit value to select the voice ADC
sampling frequency. Default 00. See
Voice ADC clock enable.
Voice ADC power control. Bit VAP is to reduce the power consumption of
the voice ADC.
DSD mode selection. Bit DSD selects the DSD 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. Bit ACE enables the audio ADC clock
ADC power control. Bit ADP is to reduce the power consumption of the
audio ADC.
