Fast Mute Mode
This feature will normally be used to suppress pop noise resulting from VCC transients during engine
cranking condition.
The fast mute mode can be entered on receipt of a command via I2C bus.
Using the IB2 register and setting to ‘one’ the bit D6, it is possible to generate a fast I2C mute command.
If a fast mute command is received, this IC will operate and will discharge the capacitor C4 at pin16.
Therefore the Pop sound will be reduced compared to the condition when Fast Mute is not used in the
engine cranking condition.
