SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
A start condition (S)
A chip address byte, containing the TDA7439
address
A subaddress bytes
A sequence of data (N byte + acknowledge)
A stop condition (P)
ACK = Acknowledge
S = Start
P = Stop
A = Address
B = Auto Increment

EXAMPLES
No Incremental Bus
The TDA7439 receives a start condition, the cor-
rect chip address, a subaddress with the B = 0
(no incremental bus), N-data (all these data con-
cern the subaddress selected), a stop condition.

Incremental Bus
The TDA7439 receive a start conditions, the cor-
rect chip address, a subaddress with the B = 1
(incremental bus): now it is in a loop condition
with an autoincrease of the subaddress whereas
SUBADDRESS from ”XXX1000” to ”XXX1111” of
DATA are ignored.
The DATA 1 concern the subaddress sent, and
the DATA 2 concern the subaddress sent plus
one in the loop etc, and at the end it receivers the
stop condition.
