§4-8. CD-DSP Block Playback Speed
In the CXD2588Q/R, the following playback modes can be selected through different combinations of the
crystal, XTSL pin and the DSPB command of $9X.

Low power consumption mode. The CD-DSP processing speed is halved, allowing power consumption
to be reduced.
§4-9. DAC Block Playback Speed
The operation speed for the DAC block is determined by the crystal and the MCSL command of $9X
regardless of the CD-DSP operating conditions noted above. This allows the playback modes for the DAC and
CD-DSP blocks to be set independently.
