• Description: Stereo Codec For Portable Audio Applications
• Manufacturer: Wolfson Microelectronics plc

Production Data
w
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 21 and Figure
22. In device slave mode, Figure 23 and Figure 24, 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.

Figure 22 DSP/PCM Mode Audio Interface (mode B, LRP=1, Master)
Figure 23 DSP/PCM Mode Audio Interface (mode A, LRP=0, Slave)
In DSP/PCM mode, the left channel MSB is available on either the 1
st
(mode B) or 2
