happens. At the same time any processing related to the I2C configuration should be issued

only after the serial audio interface and the internal PLL are synchronous again.

Any mute or volume change causes some delay in the completion of the I2C operation due

to the soft volume feature. The soft volume phase change must be finished before any clock

desynchronization.

Each channel received via I2S can be mapped to any internal processing channel via the

Channel Input Mapping registers. This allows for flexibility in processing. The default

settings of these registers map each I2S input channel to its corresponding processing

channel.
