Serial Data Output Sidechain
Setting this bit enables the SDOUT1 side chain feature. In this mode, the samples from multiple devices
can be coded into one TDM stream. See
Master / Slave
Setting this bit places the CS4244 in master mode, clearing it places it in slave.
Note:
into Master Mode.
ADCx Common Mode
Enables the ADCx input pin bias to VQ. ADC1 and ADC2 are controlled together; ADC3 and ADC4 are
controlled together. See
Note: If these bits are set to ‘1’, the ADC HPF must be enabled to achieve full specified performance.
DAC1-4 Data Source
Sets which portion of data is to be routed to the DAC1-4 data paths.
