* The duty cycle is kept unchanged thanks to an
* automatic pulse width change, in other words, the change will not be applied
* before the end of the current period. This can significantly affect reaction
* time at low frequencies. If you call the matching module <c>saveToFlash()</c>
* method, the frequency will be kept after a device power cycle.
* To stop the PWM signal, do not set the frequency to zero, use the set_enabled()
* method instead.
