TDA7443D
SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
s
A start condition (S)
s
A chip address byte, containing the TDA7440D address
s
A subaddress bytes
s
A sequence of data (N byte + acknowledge)
s
A stop condition (P)
ACK = Acknowledge;
S = Start;
P = Stop;
A = Address;
B = Auto Increment
EXAMPLES
No Incremental Bus
The TDA7443D receives a start condition, the correct chip address, a subaddress with the B = 0 (no incremental
bus), N-data (all these data concern the subaddress selected), a stop condition.
Incremental Bus
The TDA7443D receivea start conditions, the correct 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 con-
cern the subaddress sent plus one in the loop etc, and at the end it receivers the stop condition.
