2.19.13 Fine Frequency Adjust
After the course frequency is determined with the clock and period controls, the
frequency is fine tuned with the Fine Frequency Adjust control. Click on the FFA box to

The combination box in the center of the fixed frequency adjust control shows 16
possible selections based on the psmc_clk frequency and period count. Selections
possible selections based on the psmc_clk frequency and period count. Selections
can be made by frequency or time by clicking on the desired display mode radio button.
When any of the clock frequency, period frequency, or selection mode is changed, then
the selection list and displayed selection are updated to correspond to the change.
Note that the displayed frequency is twice the output waveform frequency because the
fixed 50% duty cycle is derived by dividing the adjusted period frequency by two.
