In I
The other bits up to the LSB are then transmitted in order. Depending on word length, BCLK
frequency and sample rate, there may be unused BCLK cycles between the LSB of one sample and
the MSB of the next.

In DSP/PCM mode, the left channel MSB is available on either the 1
rising edge of BCLK (selectable by FRAMEP) following a rising edge of FRAME. 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.
FRAMEP should be set to 0 in this mode.
