Software specifications

All the functions of the TDA7563B are activated by I2C interface.

The bit 0 of the "Address Byte" defines if the next bytes are write instruction (from µP to

TDA7563B) or read instruction (from TDA7563B to µP).

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.
