S mode, the MSB of the ADC data is output on DOUT and changes on the first falling edge of
BCLK following an ADCLRC transition and may be sampled on the rising edge of BCLK. ADCLRC is
low during the left samples and high during the right samples.

The MSB of the left channel ADC data is output on DOUT and changes on the first falling edge of
BCLK following a low to high ADCLRC transition and may be sampled on the rising edge of BCLK.
The right channel ADC data is contiguous with the left channel data (Figure 12)
