To set the duty cycle
Applies only to square waves. At power-on, the duty cycle for square waves
is 50%. You can adjust the duty cycle for a square waveform from 20%
to 80%, in increments of 1% (for frequencies above 5 MHz, the range is 40%
to 60%). The following steps show you how to change the duty cycle to 45%.
