VOLUME CONTROL (MICROCONTROLLER APPLICATION MODE)
In the microcontroller application mode (APPL = logic 1,
APP3 = logic 0) the audio output level is controlled by
volume control bits ATSB, MUSB, FS, INCR and DECR.
Mute is activated by sending the MUSB command to the
mode control register via the microcontroller interface. The
audio output level will be reduced to zero in a maximum of
120 steps (depending on the current position of the fade
counter) and taking a maximum of 3 ms. Mute, attenuation
and full scale are synchronized to prevent operation in the
middle of a word.
The counter is preset to 120 by the full scale command
The counter is preset to 30 by the attenuate command
when its value is more then 30. If the value of the
counter is less than 30 dB the ATSB command has no
effect.
The counter is preset to logic 0 by the mute command
MUSB
Attenuation (12 dB) is activated by sending the ATSB
command to the fade control register (D7)
Attenuation and mute are cancelled by sending the
full-scale command to the fade control register
(Register D3).
To control the fade counter in a continuous way, the
INCREMENT and DECREMENT commands are available
(fade control Registers D1 and D2). They will increment
and decrement the counter by 1 for each register write
operation. When issuing more than 1 step-up or
step-down command in sequence, the write repeat mode
may be used (see microcontroller application mode). An
example of volume control in this application mode is
illustrated in Fig.6.
