happens. At the same time any processing related to the I
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 I
to the soft volume feature. The soft volume phase change must be finished before any clock
desynchronization.

Table 22.
Each channel received via I
Channel Input Mapping registers. This allows for flexibility in processing. The default
settings of these registers map each I
channel.
