AUDIO DATA FORMATS
In Right Justified mode, the LSB is available on the last rising edge of BCLK before a LRCLK transition.
All other bits are transmitted before (MSB first). Depending on word length, BCLK frequency and sample
rate, there may be unused BCLK cycles after each LRCLK transition.
Figure 16 Right Justified Audio Interface (assuming n-bit word length)
In Left Justified mode, the MSB is available on the first rising edge of BCLK following a LRCLK transition.
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 before each LRCLK transition.

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.
