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

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.
