{{underline|Notes:}}
* {{fname|PWM}} class must have a {{fname|Pin}} instance as argument.
* {{fname|duty_u16()}} must have an 16 bits integer value (0 to 65534) for the duty cycle.
* The effective '''Max duty_u16() value is 65534'''. A regression bug would make the 65535 (real max of 16 bits) equivalent to 0 !?!?!... this Phenix bug is coming back again and again.
