        With parts that are EPROM/OTP, once you set CP that's it, no way to "unset"
it (actually physically it's the other way around I think but lets ignore
that for now...). Some parts WILL unset if left in UV long enough,
unfortunately some discovered that if they focused a UV laser right on that
part of the chip it would be possible to disable code protection but leave
the rest of the code intact. MCHIP now puts a "sheild" above where this bit
is to prevent that. TTYL
