These bits are used to set the volume of each source. The volume setting consists of 31 steps and mute function. It is
possible to set at 1dB intervals. As the default is muted, cancel the mute function before proceeding to sound generation.
Also, to reduce the power, be sure to mute the volume subject to power reduction before shifting.

This setting is used to reduce the power of each function. It is possible to control 1 digital system and 4 analog systems
independently. (For the details, please refer to "Power-down control division diagram".)
Setting all bits to "1" will minimize the power of the entire LSI.
DP : Use of "1" for this setting will reduce the power of the entire digital section.
AP1 : Use of "1" for this setting will reduce the power of the VREF circuit in the analog section.
AP2 : Use of "1" for this setting will reduce the power on the non-inverted amplifier side of the FM volume, speaker
volume, equalizer circuit and speaker output section.
AP3 : Use of "1" for this setting will reduce the power of the inverted amplifier side of the speaker output section.
AP4 : Use of "1" for this setting will reduce the power of the DAC and ear phone output volume.
After initialization, the power of the analog section (AP1 to AP4) is reduced.
