Channel Volume as a function of CxV(7..0)
3.17 Channel Input Mapping Channels 1 & 2 (address 11h)
3.18 Channel Input Mapping Channels 3 & 4 (address 12h)
3.19 Channel Input Mapping Channels 5 & 6 (address 13h)
3.20 Channel Input Mapping Channels 7 & 8 (address 14h)
Each channel received via I2S can be mapped to any internal processing channel via the Channel Input Map-
ping registers. This allows for flexibility in processing, simplifies output stage designs, and enables the ability
to perform crossovers. The default settings of these registers map each I2S input channel to its corresponding
processing channel.
For example, to map input 2 to Channel 5, set Address 11h, bits D6, D5 and D4 to 100. Now, inputs 2 and 5 go
to Channel 5.
