Hi -

What happens if you try to re-program it now, using the ICD2? The first
time you program it, it would still have a MCLR, so it should work, but
after that it doesn't have one anymore...

These parts have a new programming spec where you are supposed to turn
on the programming voltage (Vpp) before powering the chip (Vdd). I'm
guessing this is to get around the potential problem of not having a
MCLR line to reset the chip. I imagine that the PICKIT and probably the
PICStart are using this method. But since the ICD 2 doesn't
(necessarily) have control over Vdd, I don't see how it can use this method.

So, before I render my chip no longer programmable - has anyone been
able to re-program a part, whose MCLR has been set to internal, using
the ICD 2?
