Notice)
In the partial power down mode, master volume is not muted, so all analog input sources and
enabled digital sources (i.e. FM, SB, WSS etc.) can be heard. Note that AUX2 inputs are
exceptions in this regard since setting FMDAC bit inhibits the inputs altogether.

default : 00h
Channel by 1.5dB step(Max. 10.5dB).
Notice)
The 3D Enhanced control parameter registers at index 14h, 15h and 16h must be 00h, when
doing the Wide Stereo portion in power down mode (setting SA3 control register, index 13h,
WIDE bit to “1”).
