The duty cycle is defined as the percent of time that the output is high. A 50% duty cycle represents a square wave (equal high and low periods), while a duty cycle of 0% means always low and a duty cycle of 100% means always high. The range for duty cycle is 0 to 99.99 in steps of .01. a duty cycle of 100% is not possible with this function.
<p>
The function takes as inputs the desired counter, output frequency, and duty cycle. It returns status information indicating the selected input frequency, the resulting load and hold register values, and a flag indicating whether the function has reached either duty cycle limit.
