... I C BUS INTERFACE Data transmission from microprocessor to the TDA7467 and vice versa takes place through the 2 wires BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). Data Validity As shown in fig. 1, the data on the SDA line must be stable during the high period of the clock. The HIGH and LOW state of the data line can only change when the clock signal on the SCL line is LOW ...

... D96AU421mod Incremental Bus The TDA7467 receive a start conditions, the correct chip address, a subaddress with the MSB = 1 (incre- mental bus): now loop condition with an autoincrease of the subaddress whereas SUBADDRESS from "1XXXX1XX" to "1XXX111" 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 ...
