Device for transmitting sensor data

The device has manipulation unit that receives master-data input signal (DIN-M) of master interface (18) and sensor-data signal (S-M), and outputs slave-data output signal (DOUT-S) to slave interface (12). A protocol unit receives protocol-relevant interface signals (DIN-S,TCLK-S) of slave interface or master interface and sensor-data signal, and generates sensor-data output signal. The protocol unit selects protocol-relevant interface signal based on manipulation rules, when manipulation unit outputs master-data input signal or sensor-data output signal.
