16    combinations. The details are all in the datasheets but I will try
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
28    have support for surround sound. It has several outputs: MAIN, AUX, I2S
29    and SCART1/2. Each output can select which DSP input to use. So the MAIN
33    Outputs
36    Most DSP outputs are also the outputs of the msp3400. However, the SCART
37    outputs of the msp3400 can select which input to use: either the SCART1 or
48    2) which SCART input to use
56    ignore or mute certain inputs or outputs.
59    outputs may be present. At the end of this header some tables are
65    2) the SCART input
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.
