Description of the audio processor part
Programmable input matrix
The programmable input matrix of the TDA7460ND offers several possibilities to adapt the
audioprocessor to the desired application. In to the standard application we have:
CD quasi differential

The input matrix can be configured by only 2 bits: bits 3 and 4 of subaddress 0. Basically the
bit of subaddress 13 is fixed by the application and has to be programmed only once at the
startup of the IC.
For many configurations the two bits are also fixed during one application (e.g. the standard
application) and a change of the input source can be done by loading the first three bits of
subaddress 0.
In other configurations for some sources a programming of bit 3 and 4 of subaddress 0 is
necessary in addition to the three source selection bits. In every case only the subaddress 0
has to be changed to switch from one source to another.
The following picture shows the input and source programming flow:
