PD, Rev 4.1, August 2012

In DSP/PCM mode, the left channel MSB is available on either the 1

st (mode B) or 2nd (mode A) rising

edge of BCLK (selectable by LRP) following a rising edge of LRC. 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.

In device master mode, the LRC output will resemble the frame pulse shown in Figure 20 and Figure

21. In device slave mode, Figure 22 and Figure 23, it is possible to use any length of frame pulse less

than 1/fs, providing the falling edge of the frame pulse occurs greater than one BCLK period before

the rising edge of the next frame pulse.
