Software specifications

All the functions of the TDA7563A are activated by I2C interface.

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

P to

TDA7563A) or read instruction (from TDA7563A to µP).

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.
