/**
 * Retrieves a PWM input for a given identifier.
 * The identifier can be specified using several formats:
 *
 * - FunctionLogicalName
 * - ModuleSerialNumber.FunctionIdentifier
 * - ModuleSerialNumber.FunctionLogicalName
 * - ModuleLogicalName.FunctionIdentifier
 * - ModuleLogicalName.FunctionLogicalName
 *
 *
 * This function does not require that the PWM input is online at the time
 * it is invoked. The returned object is nevertheless valid.
 * Use the method isOnline() to test if the PWM input is
 * indeed online at a given time. In case of ambiguity when looking for
 * a PWM input by logical name, no error is notified: the first instance
 * found is returned. The search is performed first by hardware name,
 * then by logical name.
 *
 * If a call to this object's is_online() method returns FALSE although
 * you are certain that the matching device is plugged, make sure that you did
 * call registerHub() at application initialization time.
 *
 * @param func : a string that uniquely characterizes the PWM input, for instance
 *         YPWMRX01.pwmInput1.
 *
 * @return a YPwmInput object allowing you to drive the PWM input.
