1. A method, comprising: retrieving, by a control module in a physical layer device, configuration parameters from a control register; and configuring, by the control module, a wave shaping function implemented by a wave shaping module in the physical layer device based on the retrieved configuration parameters, the wave shaping module configured to apply a wave shaping function to a modulated signal generated by a modulation module to control signal emissions when the wave shaped modulated signal is transmitted in a communication cable in an automotive vehicle.
