* set_pwm_out pin=%u cycle_ticks=%u value=%c : This command will
immediately configure the given pin to use hardware based
pulse-width-modulation (PWM) with the given number of
cycle_ticks. The "cycle_ticks" is the amount of time (in MCU clock
ticks) in a complete power on and power off cycle. A cycle_ticks
value of 1 can be used to request the fastest possible cycle
time. The specified "value" is between 0 and 255 with 0 indicating a
full off state and 255 indicating a full on state. This command may
be useful for enabling CPU and nozzle cooling fans.
cycle_ticks. The "cycle_ticks" is the number of MCU clock ticks each
