CXD3018Q/R
The attenuation data consists of 11 bits, and is set as follows.
Attenuation data
400h
Audio output
0dB
The attenuation data (AD10 to AD0) consists of 11 bits,
and can be set in 1024 different ways in the range of
000h to 400h.
3FFh
3FEh
:
–0.0085dB
–0.0170dB
The audio output from 001h to 400h is obtained using
the following equation.
001h
–60.206dB
– ∞

Command bit
FMUT = 1
Forced mute is on.
Forced mute is off.
FMUT = 0
FMUT can be set when OPSL2 = 1.
Command bit
Meaning
Forced synchronization mode Note)
Normal operation.
LRWO = 1
LRWO = 0
LRWO can be set when OPSL2 = 1.
Note) Synchronization is performed at the first falling edge of LRCK during reset, so there is normally no need
to set this mode. However, synchronization can be forcibly performed by setting LRWO = 1.
Processing

BSBST = 1
BSBST = 0
Bass boost is on.
Bass boost is off.
BSBST can be set when OPSL2 = 1.
Processing
Command bit
BBSL = 1
BBSL = 0
Bass boost is Max.
Bass boost is Mid.
BBSL can be set when OPSL2 = 1.
