I²C bus interface
Data transmission from the main microprocessor STCF03 and vice versa takes place
through the 2 wires I²C bus interface wires, consisting of the two lines SDA and SCL (pull-up
resistors to a positive supply voltage must be externally connected). The recommended
maximum voltage of these signals should be 3.0 V.
Data validity
As shown in
clock. The HIGH and LOW state of the data line can only change when the clock signal on
the SCL line is LOW.
Data validity on the I²C Bus
Start and stop conditions
Both DATA and CLOCK lines remain HIGH when the bus is not busy. As shown in
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. A STOP condition
must be sent before each START condition.
