... TDA7309 BUS INTERFACE Data transmission from microprocessor to the TDA7313 and viceversa takes place thru the 2 wires I BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). 3.1 Data Validity As shown in fig. 11, 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 ...
