Your message got cut off probably because you are sending paragraphs as
single long lines (don't do that).

However, hanging at 27pF cap off one of these low frequency crystals is a
bad idea, especially since it's rated for a load less than half that.  The
drive levels are very low on LP mode.  A 1Mohm scope probe will usually kill
the oscillations.
