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, DAC_SDIN3 and DAC_SDIN4 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 configured 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, two additional DAC channels on DAC_SDIN4,
and 6 channels of ADC data are output on ADC_SDOUT. Table 5 outlines the serial port channel alloca-
tions.
