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.

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.

Figure 17 Left Justified Audio Interface (assuming n-bit word length)

In I2S mode, the MSB is available on the second 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 between the LSB of one sample and the MSB of the

next.
