BCLK
Right Justified mode is where the LSB is available on the rising edge of BCLK preceding a DACLRC
transition, yet MSB is still transmitted first.
In DSP/PCM mode, the left channel MSB is available on either the 1
edge of BCLK (selectable by LRP) following a rising edge of LRC. 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.
