TsctlEDIOPWMfdDesc
From embeddedTS Manuals
Set the given DIO to begin producing PWM of the specified parameters on the given DIO num. The mfreq parameter gives the frequency in milliHertz and the uDC parameter gives the duty cycle in millionths of a percent.
If the specific DIO does not support the specified frequency and duty cycle, the closest available frequency and duty cycle will be used.
