Softmute
The digitally controlled softmute stage allows muting/demuting the signal with a I2C bus
programmable slope. The mute process can either be activated by the softmute pin or by the
I2C bus. The slope is realized in a special S shaped curve to mute slow in the critical
regions.

Softmute timing
Note:
Please notice that a started Mute action is always terminated and could not be interrupted
by a change of the mute signal.
For timing purposes the Bit 3 of the I2C bus output register is set to 1 from the start of muting
until the end of demuting.

BASS
There are four parameters programmable in the bass stage: (see figs 9, 10, 11, 12):
