w
In DSP mode, the left channel MSB is available on either the 1st (mode B) or 2nd (mode A) rising
edge of PCMCLK (selectable by FSP) following a rising edge of PCMFS. Right channel data
immediately follows left channel data. Depending on word length, PCMCLK frequency and sample
rate, there may be unused PCMCLK cycles between the LSB of the right channel data and the next
sample.
