TDA7439

6.2 Incremental Bus
The TDA7439 receive a 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 concern the subaddress sent plus one in the
loop etc, and at the end it receivers the stop condition.

Address = 88 HEX (ADDR:OPEN).
