Software specifications

All the functions of the TDA7569BLV are activated by I2C interface.

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

TDA7569BLV) or read instruction (from TDA7569BLV 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.

(*) address selector bit, please refer to address selection description on Chapter 9.2.
