DIGITAL AUDIO INTERFACE
MASTER AND SLAVE MODES
The audio interface operates in either Slave or Master mode, selectable using the MS control bit. In
both Master and Slave modes DIN1/2/3/4 are always inputs to the WM8768. The default is Slave
mode.
In Slave mode, LRCLK and BCLK are inputs to the WM8768 (Figure 11). DIN1/2/3/4 and LRCLK are
sampled by the WM8768 on the rising edge of BCLK.
By setting the control bit BCP the polarity of BCLK may be reversed so that DIN1/2/3/4 and LRCLK
are sampled on the falling edge of BCLK .

Figure 11 Slave Mode
In Master mode, LRCLK and BCLK are outputs from the WM8768 (Figure 12). LRCLK and BCLK are
generated by the WM8768. DIN1/2/3/4 are sampled by the WM8768 on the rising edge of BCLK so
the controller must output DAC data that changes on the falling edge of BCLK.
By setting control bit BCP the polarity of BCLK may be reversed so that DIN1/2/3/4 are sampled on
the falling edge of BCLK..
