You only need to purchase a license for the megafunction when you are
completely satisfied with its functionality and performance, and want to
take your design to production.

The example driver, which only demonstrates basic read and
write operation, can limit the performance, particularly in wide
interfaces. To improve performance, replace the example driver
or remove it and use the virtual pins on the controller.
