To my knowledge, those devices do not have an ARM7 in them.  You have,
therefore, not answered the question I posed.

Why would I want to do that?  As you are disparaging the LPC2000 for no
feed sequences, I would like you to provide an example commercial
(non-automotive) ARM7 with a feed sequence that provides FLASH
protection.

That still does not answer my question.  I see you have sidestepped it
very neatly, something you disparage others for.  So, it's industry
standard but there is no standard?

As you have not provided a standard reference, and have simply shirked
my questions, can I claim that it the LPC2000 series is industry
standard in not providing flash feed sequences as all other ARM7s do the
same?
