Software specifications

21/28

Software specifications

All the functions of the TDA7566 are activated by I2C interface.

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

μP to

TDA7566) or read instruction (from TDA7566 to µP).

Table 5.

Chip Address:

X = 0 Write to device

X = 1 Read from device

If R/W = 0, the

μP sends 2 "Instruction Bytes": IB1 and IB2.
