In DSP mode, the left channel MSB is available on either the 1
(selectable by LRP) following a rising edge of ADCLRC. Right channel data immediately follows left
channel data. Depending on word length, BCLK frequency and sample rate, there may be unused
BCLK cycles between the LSB of the right channel data and the next sample.
