of CODEC_BCLK following a DACLRC or ADCLRC
transition.
Right Justified Mode
Right justified mode is where the LSB is available on the rising
edge of CODEC_BCLK preceding a DACLRC or ADCLRC
transition, yet MSB is still transmitted first.
Frame Sync/PCM Mode
In frame sync/PCM mode, the left channel MSB is available on
either the first (mode B) or second (mode A) rising edge of
CODEC_BCLK (selectable by LRP) following a rising edge of
