DSP MODES

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 15 and Figure

16. In device slave mode, Figure 17 and Figure 18, 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.
