Description:
When the internal sampling clock can only take a small
discrete set of values, this file lists those available.
When the internal sampling clock can only take a specific set of
frequencies, we can specify the available values with:
- a small discrete set of values like "0 2 4 6 8"
- a range with minimum, step and maximum frequencies like
"[min step max]"
