bit[13:5] SCART DSP Input Select
xxxx00 xx0 SCART1 to DSP input (RESET position)
xxxx01 xx0 MONO to DSP input (Sound A Mono must be selected in
the channel matrix mode for the corresponding output
channels)
xxxx10 xx0 SCART2 to DSP input
xxxx11 xx0 SCART3 to DSP input
xxxx00 xx1 SCART4 to DSP input
xxxx11 xx1 mute DSP input
bit[13:5] SCART1 Output Select
xx00xx x0x SCART3 input to SCART1 output (RESET position)
xx01xx x0x SCART2 input to SCART1 output
xx10xx x0x MONO input to SCART1 output
xx11xx x0x SCART1 DA to SCART1 output
xx00xx x1x SCART2 DA to SCART1 output
xx01xx x1x SCART1 input to SCART1 output
xx10xx x1x SCART4 input to SCART1 output
xx11xx x1x mute SCART1 output
bit[13:5] SCART2 Output Select
00xxxx 0xx SCART1 DA to SCART2 output (RESET position)
01xxxx 0xx SCART1 input to SCART2 output
10xxxx 0xx MONO input to SCART2 output
00xxxx 1xx SCART2 DA to SCART2 output
01xxxx 1xx SCART2 input to SCART2 output
10xxxx 1xx SCART3 input to SCART2 output
11xxxx 1xx SCART4 input to SCART2 output
11xxxx 0xx mute SCART2 output
The RESET position becomes active at the time of the first write transmission on
the control bus to the audio processing part. By writing to the ACB register first,
the RESET state can be redefined.
