WebbI2C is a serial, synchronous, half-duplex communication protocol that allows co-existence of multiple masters and slaves on the same bus. The I2C bus consists of two lines: … WebbAll masters generate their own clock on the SCL line to transfer messages on the I2C-bus. Data is only valid during the HIGH period of the clock. A defined clock is therefore needed for the bit-by-bit arbitration procedure to take place. Clock synchronization is performed using the wired-AND connection of I2C interfaces to the SCL line.
