TDA7565
SOFTWARE SPECIFICATIONS
All the functions of the TDA7565 are activated by I2C interface.
The bit 0 of the "ADDRESS BYTE" defines if the next bytes are write instruction (from µP to TDA7565) or
read instruction (from TDA7565 to µP).

0 = Write instruction
1 = read instruction
If R/W = 0, the µP sends 2 "Instruction Bytes": IB1 and IB2.
