SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
■
A start condition (S)
■
A chip address byte, containing the TDA7442D
■
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
4.1 EXAMPLES
4.1.1 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 data concern the subaddress selected), a stop condition.
4.1.2 Incremental Bus
The TDA7442D receive a start conditions, the correct chip address, a subaddress with the MSB = 1 (in-
cremental bus): now it is in a loop condition with an autoincrease of the subaddress whereas SUBAD-
DRESS from "1XXX1010" to "1XXX1111" of DATA are ignored.
The DATA 1 concern the subaddress sent, and the DATA 2 concerns the subaddress sent plus one sent
in the loop etc, and at the end it receivers the stop condition.
