3     msp3400.h - definition for msp3400 inputs and outputs
16    combinations. The details are all in the datasheets but I will try
19    Inputs
22    There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
24    selected tuner input, the selected SCART input and all I2S inputs go to
38    SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
56    ignore or mute certain inputs or outputs.
58    Also, depending on the msp version only a subset of the inputs or
63 /* Inputs to the DSP unit: two independent selections have to be made:
66    Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
67    input, bits 4-7 are reserved.
88    There also is a quasi-peak detector output, but that is not used by
90    Not all outputs are supported by all msp models. Setting the input
93    There are up to 16 DSP inputs to choose from, so each output is

98    multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
