Description of Control Registers

TEST (1) :

DAC test mode for VCA and checking Cue BPF mode.

Use only for the electrical characteristics inspection process of IC.

0 = Normal mode

1 = Test mode, the Cue signal component through Cue BPF to TV OUT-L.

Output DAC voltage for VCA to TV OUT-R.

ATT (7) :

Perform the separation adjustment by varying the signal level input to MPX IN (Pin 5).

Variable range of the input signal: Normal input level ±3.0dB

0 = Level Min.

34 = Center

7F = Level Max.

EXT (1) :

Select TV mode or external input mode for LS OUT output

0 = TV mode

1 = External input mode

FOMO (1) :

Select ON/OFF forced MONO mode

0 = Forced MONO OFF

1 = Forced MONO ON

S1 (1) :

Select output signal for TV OUT, LS OUT

S0 (1) :

Select output signal for TV OUT, LS OUT

MUTE TV (1) :

Mute TV OUT output

0 = Mute ON

1 = Mute OFF

MUTE LS (1) :

Mute LS OUT output

0 = Mute ON

1 = Mute OFF

BASS (5) :

LS OUT output bass control

0 = Bass Min.

10 = Bass Center (0dB)

1F = Bass Max.

TREBLE (5) :

LS OUT output treble contorl

0 = Treble Min.

10 = Treble Center (0dB)

1F = Treble Max.

VOL (8) :

LS OUT output signal level control

0 = Volume Min. (–90dB Typ.)

FF = Volume Max. (0dB)

BAL (6) :

LS OUT-L, R output signal level (balance) control

0 = Lch Min., Rch Max.

20 = Center (Lch 0dB, Rch 0dB)

3F = Lch Max., Rch Min.
