TDA7430 - TDA7431

EXAMPLES
5.1 No Incremental Bus
The TDA7430/TDA7431 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 condition.
Figure 12.
5.2 Incremental Bus
The TDA7430/TDA7431 receives 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.
