		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]"
