Not definitive, but my answer is this. On chips where the programming volta=
ge is generated internally, then the algorithm internal to the chip should =
be programming it in a manner that takes care of high/low Vcc requirements.=
 If you specifically want to do a high/low Vcc verify, then feel free to bu=
st your boiler trying.
