Production Data

PD Rev 4.1 December 2006

Figure 26 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 FRAME 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.

Figure 27 I

2S Audio Interface (assuming n-bit word length)

In DSP/PCM mode, the left channel MSB is available on the 2

nd (mode A) 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.

Figure 28 DSP/PCM Mode Audio Interface (mode A)

When using ADCLRSWAP = 1 or DACLRSWAP = 1 in DSP/PCM mode, the data will appear in the

Right Phase of the FRAME, which will be 16/20/24/32 bits after the FRAME pulse.
