SOFTWARE SPECIFICATIONS
All the functions of the TDA7575PD are activated by I
The bit 0 of the "ADDRESS BYTE" defines if the next bytes are write instruction (from µP to TDA7575PD) or
read instruction (from TDA7575PD to µP).
ADDRESS SELECTION
If R/W = 0, the µP sends 2 "Instruction Bytes": IB1 and IB2.
