print out the buffer values.
Example 3
This is the example for continuous pulse train generation.
It generates continuous pulses on the
G_Out pin with a three clock delay
from the trigger, pulse interval of four clocks, and pulsewidth of three
clocks.
G_in_timebase (20 MHz) is G_source. The waveform
