SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
A start condition (s)
A chip address byte, containing the TDA7319
TDA7319
address (the 8th bit of the byte must be 0). The
TDA7319 must always acknowledge at the end
of each transmitted byte.
A sequence of data (N-bytes + acknowledge)
A stop condition (P)
