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.

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 output 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 in the range of 000h

to 400h.

The audio output from 001h to 400h is obtained using the

following equation.

Audio output = 20log
