4. Mixer Register :
All mixer register access with odd-number will return with 0.
Reading unimplemented registers will return 0.
MX00
Reset
Default : 5800h
Bit Type
Function
15 Reserved
14:10
R return 16H
9 R Read as 0 (No support 20-bit ADC)
8 R Read as 0 (No support 18-bit ADC)
7 R Read as 0 (No support 20-bit DAC)
6 R Read as 0 (No support 18-bit DAC)
5 R Read as 0 (No support for Loudness)
4 R Read as 0 (No HeadPhone-Out support)
3 R Read as 0 (No simulated stereo ,for analog 3D block use)
2 R Read as 0 (No Bess & Treble Control)
1 R Reserved,Read as 0
0 R Read as 0 (No Dedicated Mic PCM input)
ΠWrite to this register will reset all mixer registe2r to their default value. The write data is
ignored.
MX02
Master Volume
Default : 8000h
Bit Type
Function
15 R/W Mute Control 0 : Normal 1 : Mute (-¥ dB)
14:13
Reserved
12:8 R/W Master Left Volume (MLV[4..0]) in 1.5 dB step
7:5 Reserved
4:0 R/W Master Right Volume (MRV[4..0]) in 1.5 dB step
ΠFor MRV/MLV,
00h 0 dB attenuation
1Fh 46.5 dB attenuation
• MRV/MLV are 5-bit R/W variables. The 6th bit implementation is optional. For this reason,
when 6th bit is written by 1,it is equivalent to writing low 5-bit with 1. For example, writing
MX04
1xxxxx will read back 01111.
Line Level Output Volume
Default : 8000h
Bit Type
Function
15 R/W Mute Control 0 : Normal 1 : Mute (-¥ dB)
14:13
Reserved
12:8 R/W Line Level Output Left Volume (LNLV[4..0]) in 1.5 dB step
7:5 Reserved
4:0 R/W Line Level Output Right Volume (LNRV[4..0]) in 1.5 dB step
ΠFor LNRV/LNLV,
00h 0 dB attenuation
1Fh 46.5 dB attenuation
•Implement 5-bit volume control only. Writing 1xxxxx will be interpreted as x11111 and
response when read with x11111 too.
MX06
MONO_OUT Volume
Default : 8000H
Bit Type
Function
15 R/W Mute Control 0 : Normal 1 : Mute (-¥ dB)
14:5 Reserved
4:0 R/W Mono Master Volume (MMV[4..0]) in 1.5 dB step
ΠFor MMV,
00h 0 dB attenuation
1Fh 46.5 dB attenuation
•Implement 5-bit volume control only. Writing 1xxxxx will be interpreted as x11111 and
