8.7.8.9
Bass boost
A 4-bit value to program the bass boost setting in
combination with the filter mode settings. At f
s
= 44.1 kHz
the
3 dB point for minimum setting is 250 Hz and the
3 dB point for maximum setting is 300 Hz. The default
value is ‘0000’.

8.7.8.10
De-emphasis
A 2-bit value to enable the digital de-emphasis filter.

8.7.8.11
Soft mute
A 1-bit value to enable the digital mute.

8.7.8.12
Volume control
A 6-bit value to program the left and right channel volume
attenuation. The range is from 0 to
dB in steps of 1 dB.

8.7.8.13
Auto mute
A 1-bit value to activate mute during out-of-lock. In normal
operation the output is automatically hard muted when an
out-of-lock situation is detected. Setting this bit to logic 0
will disable that function.
