6.2.5

Channel input mapping

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.

6.3

Configuration register C (addr 0x02)

6.3.1

DDX® power output mode

The DDX power output mode selects how the DDX output timing is configured.
