+Using a two-level configuration register scheme ensures that when a (part of) a
+particular configuration is reused in more then one sequencer instruction, it
+does not have to be duplicated entirely. Only the index pointing to the right
+configuration register (which is a lot smaller) is duplicated in multiple
+sequencer instructions. This does of course limit the amount of different
+configurations that a single program can use and thus limit the size of a
+Montium program.
