bits in the register “Interface Formats (address 04h)” on page 34. The serial audio data is presented in 2's
complement binary form with the MSB first in all formats.
DAC_SDIN1, DAC_SDIN2, and DAC_SDIN3 are the serial data input pins supplying the internal DAC.
ADC_SDOUT, the ADC data output pin, carries data from the two internal 24-bit ADCs and, when con-
figured for one-line mode, up to four additional ADC channels attached externally to the signals ADCIN1
and ADCIN2 (typically two CS5361 stereo ADCs). When operated in One Line Data Mode, 6 channels of
DAC data are input on DAC_SDIN1 and 6 channels of ADC data are output on ADC_SDOUT. Table 5
outlines the serial port channel allocations.
