Description of the audio processor part
4.1.1
How to find the right input configuration
The best way to come to the desired configuration may be to go through the application tree
from the top to the bottom while making the specific decisions.
This way will lead to one of the six possible applications. Then take the number of the
application and go into the pinning table. Here you will find the special pinout as well as the
special programming codes for selecting sources.
For example in Appl. 6 the TDA7460ND has to be configured while startup with the databyte
0/xxxx0xxx.
To select the FM, AM or phone source the last five significant bits of subaddress 0 have to
be changed, for any other source the last three bits are sufficient (see Section 7: Data byte
Table 7.
