Product specification
Digital TV Sound Processor (DTVSP)
TDA9875A
10.3.15 A
UDIO MUTE CONTROL REGISTER
When any of these bits are set to logic 1, the corresponding pair of output channels will be muted. A bit set to logic 0
allows normal signal output.
There is a soft mute facility for the Main and Auxiliary output channels to provide click-free muting independent of the
volume control. This is switched on/off by bits MUTMAIN and MUTAUX.
Table 36
Subaddress 18 (note 1)
Note
1.
The default setting at power-up is 1111 1111.
10.3.16 DAC
OUTPUT SELECT REGISTER
This register is used to define both the signal source to be entered into the DAC and the mode of the digital matrix for
signal selection. The DAC is used for signal output from digital sources at analog outputs.
The bits DACGAIN1 and DACGAIN2 can introduce some extra gain at the input to the DAC; DACGAIN1 adds 3 dB and
DACGAIN2 adds 6 dB of gain, respectively.
The two combinations of FM and NICAM apply to the (rare) condition that three different languages are being broadcast
in an FM + NICAM system. They allow for a two-out-of-three selection for external use, such as recording.
