The MSB of the left channel ADC data is output on DOUT and changes on the first falling edge of
ADCBCLK following a low to high ADCLRC transition and may be sampled on the rising edge of
ADCBCLK. The right channel ADC data is contiguous with the left channel data (Figure 17)
Figure 17 DSP Mode A Timing Diagram – ADC Data Output
DSP MODE B
In DSP mode B, the MSB of DAC left channel data is sampled by the WM8569 on the first
DACBCLK rising edge following a DACLRC rising edge. (Figure 18).
Figure 18 DSP Mode B Timing Diagram – DAC Data Input
The MSB of the left channel ADC data is output on DOUT and changes on the same falling edge of
ADCBCLK as the low to high ADCLRC transition and may be sampled on the rising edge of
ADCBCLK. The right channel ADC data is contiguous with the left channel data (Figure 19).
