The MSB of the left channel ADC data is output on DOUT and changes on the same falling edge of

ADCBCLK as the low to high ADCLRC transition and may be sampled on the rising edge of

ADCBCLK. The right channel ADC data is contiguous with the left channel data (Figure 56).

In both DSP mode A and mode B , DACL1 is always sent first, followed immediately by DACR1 and

the data words for the other 6 channels. No BCLK edges are allowed between the data words. The

word order is DAC1 left, DAC1 right, DAC2 left, DAC2 right, DAC3 left, DAC3 right.
