Low power consumption mode. The CD-DSP processing speed is halved, allowing the power
consumption to be decreased.
(B) 1-bit DAC block
The operating speed of the DAC block is determined by the crystal and the $9X command MCSL
regardless of the operating conditions of the CD-DSP block mentioned above. This allows the playback
mode for the DAC block and CD-DSP block to be set independently.
