Yes, it's the idea of xtimer to make use of the lowest power timer, however,
this hasn't been implemented as far as I know. Probably, Kaspar or Joakim
could shed some more light on the implementation status. Particular about the
support for frequencies below 1MHz.

The bad thing about HTML DOM jokes is that everyone has their own
interpretations, so you have to tell them 9000 different ways.
