The M3L-bus is a single master protocol which consists of 3-wire bus; the SCL(clock),SDA(data), and I2CEN (for START and STOP condition). The clock frequency can achieve up to 1.0 MHz that means faster data transfer rate as the I2C Bus. The
microcontrollers from Siemens have a hardware interface which can be used for M3L-bus protocol. This software module is using the hardware peripheral of High-Speed
Synchronous Serial Channel for the C16X microcontroller family.
