TDA7303 I2C bus interface 2 3 I C bus interface Data transmission from microprocessor to the TDA7303 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 Figure20, 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 Figure21 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. 3.3 Byte format Every byte transferred on the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit. The MSB is transferred first. 3.4 Acknowledge The master (P) puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see Figure22). The peripheral (audioprocessor) that acknowledges has to pull-down (low) the SDA line during the acknowledge clock pulse, so that the SDA line is stable low during this clock pulse. The audioprocessor which has been addressed has to generate an acknowledge after the reception of each byte, otherwise the SDA line remains at the high level during the ninth clock pulse time. In this case the master transmitter can generate the stop information in order to abort the transfer. 3.5 Transmission without acknowledge Avoiding to detect the acknowledge of the audioprocessor, the P can use a simpler transmission: simply it waits one clock without checking the slave acknowledging, and sends the new data. This approach of course is less protected from misreading and decreases the noise immunity. 13/20
