AUDIO DATA FORMATS (NORMAL MODE)

In Right Justified mode, the LSB is available on the last rising edge of BCLK before a ADCLRC

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 ADCLRC transition.

Figure 35 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 ADCLRC

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 ADCLRC

transition.

Figure 36 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 ADCLRC 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.
