Software specifications
All the functions of the TDA7564B are activated by I
The bit 0 of the "Address byte" defines if the next bytes are write instruction (from µP to
TDA7564B) or read instruction (from TDA7564B to µP).
X = 0 Write to device
X = 1 Read from device
If R/W = 0, the μP sends 2 "Instruction bytes": IB1 and IB2.
