   To elaborate just a bit, if you are using a 3.3 volt or anything
below a 5.0 volt Vcc, you will probably want to use the lower, 2.7 volt
BODLEVEL setting.  If you are using a 5V or higher Vcc, you will
probably want to use the 4 volt BODLEVEL setting.   It can be a little
more complicated than that for some specialized applications, but in
geeneral, these rules of thumb should suffice.
