Registers 38-41: DAC Channel Mapping

The DAC channel mapping registers are used to map the internal data path to the analog section. Any one of the 8

decoded input channels can be mapped to any of the 8 output DAC channels. By default , in1 will map to DAC1, etc.

Each DAC has a 4-bit register that assigns the input channel.
