TDA7429L
3I2C BUS INTERFACE
Data transmission from microprocessor to the TDA7429L and viceversa takes place through the 2 wires I2C
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. 5, 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.
3.2 Start and Stop Conditions
As shown in fig.6 a start condition is a HIGH to LOW transition of the SDA line while SCL is HIGH. The stop
condition is a LOW to HIGH transition of the SDA line while SCL is HIGH.
