Interface Protocol
The interface protocol comprises:
A start condition (s)
A chip address byte, containing the TDA7303 address (the 8th bit of the byte must be
0).
The TDA7303 must always acknowledge at the end of each transmitted byte.
A sequence of data (N-bytes + acknowledge)
A stop condition (P)
ACK = Acknowledge
S = Start
P = Stop
MAX CLOCK SPEED 100kbits/s
