Software specifications
All the functions of the TDA7567PD are activated by I2C interface.
The bit 0 of the "Address Byte" defines if the next bytes are write instruction (from P to
TDA7567PD) or read instruction (from TDA7567PD to P).
Chip address
X = 0 Write to device
X = 1 Read from device
If R/W = 0, the P sends 2 "Instruction Bytes": IB1 and IB2.
