45-6 Industrial Communication Systems

e duty cycle parameters are very important for the waveform of the LIN signal. ey establish

limits that ensure the correct determination of the logical bit value for the serial communication inter-

face (SCI) of the receiver. ey cover the issues of dri, oscillator tolerances, and asymmetries of

receiver propagation delay rising edge with respect to the falling edge [TR0363].
