Audio output
Command bit
EMPH = 1
EMPH = 0
De-emphasis is on.
De-emphasis is off.
Processing
If either the EMPHI pin or EMPH is high, de-emphasis is on.
If either the SMUT pin or SMUT is high, soft mute is on.
Command bit
SMUT = 1
SMUT = 0
Soft mute is on.
Soft mute is off.
Processing
Command bit
AD9 to 0
Attenuation data.
Meaning
Command bit
Mute = 1
Mute = 0
CD-DSP block mute is on. 0 data is output from the CD-DSP block.
CD-DSP block mute is off.
Processing
Command bit
ATT = 1
ATT = 0
CD-DSP block output is attenuated (
–
12dB).
CD-DSP block attenuation is off.
Processing
Command bit
OPSL2 = 1
OPSL2 = 0
FMUT, LRWO, BSBST and BBSL can be set.
FMUT, LRWO, BSBST and BBSL cannot be set.
Meaning
The attenuation data (AD10 to AD0) consists of 11bits,
and can be set in 1024 different ways.
The audio output from 001h to 400h is obtained using the
following equation.
Audio output = 20log [dB]
