The details are all in the datasheets but I will try - to give a short description here. - - Inputs - ====== - - There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have - to select which tuner input to use and which SCART input to use. The - selected tuner input, the selected SCART input and all I2S inputs go to - the DSP (the tuner input first goes through the demodulator). - - The DSP handles things like volume, bass/treble, balance, and some chips - have support for surround sound. It has several outputs: MAIN, AUX, I2S - and SCART1/2. Each output can select which DSP input to use. So the MAIN - output can select the tuner input while at the same time the SCART1 output - uses the I2S input. - - Outputs - ======= - - Most DSP outputs are also the outputs of the msp3400. However, the SCART - outputs of the msp3400 can select which input to use: either the SCART1 or - SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely - bypassing the DSP. - - Summary - ======= - - So to specify a complete routing scheme for the msp3400 you will have to - specify in the 'input' arg of the s_routing function: - - 1) which tuner input to use - 2) which SCART input to use - 3) which DSP input to use for each DSP output - - And in the 'output' arg of the s_routing function you specify: - - 1) which SCART input to use for each SCART output - - Depending on how the msp is wired to the other components you can - ignore or mute certain inputs or outputs. - - Also, depending on the msp version only a subset of the inputs or - outputs may be present. At the end of this header some tables are - added containing a list of what is available for each msp version. - */ - -/* Inputs to the DSP unit: two independent selections have to be made: - 1) the tuner (SIF) input - 2) the SCART input - Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner - input, bits 4-7 are reserved. - */ - -/* SCART input to DSP selection */ -#define MSP_IN_SCART1 0 /* Pin SC1_IN */ -#define MSP_IN_SCART2 1 /* Pin SC2_IN */ -#define MSP_IN_SCART3 2 /* Pin SC3_IN */ -#define MSP_IN_SCART4 3 /* Pin SC4_IN */ -#define MSP_IN_MONO 6 /* Pin MONO_IN */ -#define MSP_IN_MUTE 7 /* Mute DSP input */ -#define MSP_SCART_TO_DSP(in) (in) -/* Tuner input to demodulator and DSP selection */ -#define MSP_IN_TUNER1 0 /* Analog Sound IF input pin ANA_IN1 */ -#define MSP_IN_TUNER2 1 /* Analog Sound IF input pin ANA_IN2 */ -#define MSP_TUNER_TO_DSP(in) ((in) << 3) - -/* The msp has up to 5 DSP outputs, each output can independently select - a DSP input. - - The DSP outputs are: loudspeaker output (aka MAIN), headphones output - (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output. - There also is a quasi-peak detector output, but that is not used by - this driver and is set to the same input as the loudspeaker output. - Not all outputs are supported by all msp models.
