SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
A start condition (S)
A chip address byte, containing the TDA7430
/TDA7431 address
A subaddress bytes
A sequence of data (N byte + achnowledge)
A stop condition (P)
ACK = Achnowledge
S = Start
P = Stop
A = Address
B = Auto Increment

EXAMPLES
No Incremental Bus
The TDA7430 /TDA7431 receives a start condi-
tion, the correct chip address, a subaddress with
the MSB = 0 (no incremental bus), N-datas (all
these datas concern the subaddress selected), a
stop condition.

Incremental Bus
The TDA7430 /TDA7431 receive s a start condi-
tion, the correct chip address, a subaddress with
the MSB = 1 (incremental bus): now it is in a loop
condition with an autoincrease of the subaddress
whereas SUBADDRESS from "1XXX1010" to
"1XXX1111" of DATA are ignored.
The DATA 1 concern thesubaddress sent, and
the DATA 2 concern the subaddress sent plus
one in the loop etc, and at the end it receivers the
stop condition.
