TDA7404
I2C bus interface
Note:
With this programming all the outputs are muted to VREF (VOUT= VDD/2).
All the blank bits in the following tables are "don't care"-bits.

1. For more information seeSection 4.5: Soft-mute.
2. For more information see Section 4.2: AutoZero
3. For more information see Test Programming block
4. If this bit is set to "1", the subaddress is automatically increased after the transmission of a data-byte.
Therefore a transmission of more than one byte without sending the new subaddress is possible.
