WM8980

PP Rev 1.6 January 2005

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

Figure 25 Right Justified Audio Interface (assuming n-bit word length)

In I

2S mode, the MSB is available on the second rising edge of BCLK following a LRC 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.
