SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
A start condition (S)
A chip address byte, containing the TDA7442D
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 TDA7442D receives a start condition, the
correct chip address, a subaddress with the MSB
= 0 (no incremental bus), N-datas (all these datas
concern the subaddress selected), a stop condi-
tion.

Incremental Bus
The TDA7442D receive s a start condition, 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.
