I'll go back and recheck the programming spec for the 18LF2320, but
I seem to recall that it is, in fact, important that the verification at
least take place at the voltage designated for the final product.

Also, it seems foolish to me to make a product like the ICD2 which is
capable of programming at the system voltage, to go to lengths to
ensure it can be done, but then not put a simple provision in to warn
the user that, wait, you need to program this at a higher voltage.

Although no one here believes that Microchip would do ANYTHING
foolish.  ;-)
