§4-9. DAC Block Playback Speed
The DAC block playback speed is controlled by sending the DADS command to the DSP block.

§4-10. DAC Block Input Timing
The DAC input timing chart is shown below.
Audio data is not transferred from the CD signal processor block to the DAC block inside the CXD3000R. This
is to allow data to be sent to the DAC block via the audio DSP, etc.
When the data is input to the DAC block without using the audio DSP, the data must be connected outside the
LSI. In this case, LRCK, BCK and PCMD can be connected directly with LRCKI, BCKI and PCMDI,
respectively. (See the Application Circuit.)
