3     msp3400.h - definition for msp3400 inputs and outputs
22    There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
23    to select which tuner input to use and which SCART input to use. The
24    selected tuner input, the selected SCART input and all I2S inputs go to
25    the DSP (the tuner input first goes through the demodulator).
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
30    output can select the tuner input while at the same time the SCART1 output
31    uses the I2S input.
37    outputs of the msp3400 can select which input to use: either the SCART1 or
45    specify in the 'input' arg of the s_routing function:
47    1) which tuner input to use
48    2) which SCART input to use
49    3) which DSP input to use for each DSP output
53    1) which SCART input to use for each SCART output
64    1) the tuner (SIF) input
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.

88    There also is a quasi-peak detector output, but that is not used by
