C bus
2.0 SOFTWARE SPECIFICATION
2.1 Interface Protocol
The interface protocol comprises:
I
A start condition (S)
I
A chip address byte, containing the TDA7429L address
I
A subaddress bytes
I
A sequence of data (N byte + achnowledge)
I
A stop condition (P)
3.0 EXAMPLES
3.1 No Incremental Bus
The TDA7429L receives a start condition, the correct chip address, a subaddress with the MSB = 0 (no incre-
mental bus), N-datas (all these datas concern the subaddress selected), a stop condition.
3.2 Incremental Bus
The TDA7429L receives a start condition, the correctchip 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.
