DAC Volume Update
Writing a 1 to this bit will cause left and right
DAC volumes to be updated (LDACVOL and
RDACVOL)
Left DAC Digital Volume Control
0000 0000 = Digital Mute
0000 0001 = -127dB
0000 0010 = -126.5dB
... 0.5dB steps up to
1111 1111 = 0dB

3D Enhance Filter Upper Cut-Off Frequency
0 = High (Recommended for fs>=32kHz)
1 = Low (Recommended for fs<32kHz)
3D Enhance Filter Lower Cut-Off Frequency
0 = Low (Recommended for fs>=32kHz)
1 = High (Recommended for fs<32kHz)
3D Stereo Depth
0000 = 0% (minimum 3D effect)
0001 = 6.67%
....
1110 = 93.3%
1111 = 100% (maximum 3D effect)
3D Stereo Enhancement Enable
0 = Disabled
1 = Enabled
ALC Function Select
00 = ALC off (PGA gain set by register)
01 = Right channel only
10 = Left channel only
11 = Stereo (PGA registers unused) Note:
ensure that LINVOL and RINVOL settings
(reg. 0 and 1) are the same before entering
this mode.
