OUTPUT SELECT REGISTER
10.3.20.1 Description
This register is used to define the signal source for the ADC. There is no output channel selector, because all digital
signal sinks of the ADC have their own matrix. Instead, a level adjustment facility for the ADC output is provided.

FUNCTION
LINSEL
HIGH
Specifies that a signal from an analog source is being processed in the Main channel.
Analog signal sources comprise SCART 1 input, SCART 2 input, external input and
mono input, i.e. any input to the ADC.
Specifies that a signal from a digital source is being processed in the Main channel.
Digital signal sources comprise FM, NICAM, I
2
S1 input and I
2
S2 input.
Activates the 3 dB gain stage at the line output port.
The audio signal will be output unchanged (0 dB gain).
