 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]"
