bit[13:5] SCART DSP Input Select
xxxx00xx0 SCART1 to DSP input (RESET position)
xxxx01xx0 MONO to DSP input (Sound A Mono must be selected in
the channel matrix mode for the corresponding output
channels)
xxxx11xx1 mute DSP input
bit[13:5] SCART1 Output Select
xx00xxx0x undefined (RESET position)
xx10xxx0x MONO input to SCART1 output
xx11xxx0x SCART1 DA to SCART1 output
xx01xxx1x SCART1 input to SCART1 output
xx11xxx1x mute SCART1 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.
