The frequency of the PWM module is set no more than 10% lower than the timing signal frequency. The modules may combine the combined signal with an inverted output of the PWM X-bar to generate a local module data signal Rx which is passed to a data signal decoder 62. An asynchronous bidirectional data network may transfer additional data between the controller and modules; such as: voltage, current and temperature measurements.
