This is the main function used to generate PWM signals on the 
Hercules-EBX.  Please consult the Hercules user manual for more information on the PWM circuit.  This function can also be used with the 
Quartz-MM family of boards, but we recommend using the 
dscQMMPulseWidthModulation() function for maximum compatibility.
