(MDACOSR)
This register is used to define the signal source to be
entered into the mono DAC. The mono DAC is used for
signal output from digital sources.
For the mono DAC output auto-matrix switching is always
active.
In stereo mode
is chosen automatically. Selecting
Language B (MDOS1, MDOS0 = 01 or 11) will only show
effect, while a dual transmission via FM A2 or NICAM is
being received.
Settings in the FM dematrix register have no effect on the
source selection for the mono DAC.
The level adjustment for an FM source is determined by
the Channel 1 output level adjustment register
(subaddress 12) for mono/dual A, or by the Channel 2
output level adjustment register (subaddress 13) for
dual B, or by the NICAM output level adjustment register
(subaddress 15) if a NICAM source is selected.
Some extra gain can be introduced at the input to the DAC
to provide a coarse level adjustment function.
The default setting after power-on reset is ‘0000 0000’.
Bits 2, 4, 5 and 6 are don’t care and should be set to
logic 0.
