To clarify: the quote used above comes from the LPC213x User Manual, 
under the Features list (section 1.2). It's also in plenty of other 
Philips documentation and promotional material.

It never occured to me that the statement above was in any way 
controversial, or would need its source cited.

As Philips, I and others have pointed out, the program memory can 
also be used for non-volatile data storage by an application. As 
we've also all pointed out, you need to look carefully at your exact 
requirements when used for this purpose as the flash is far from 
optimised for this usage; it is not suitable as a straight 
replacement for a generic EEPROM. The 400ms erase time is just one 
example of this.

I did not believe, nor do I now believe, that this is in any way 
controversial. 

Anyone trying to manufacture controversy over this issue is wasting 
their own and, more importantly, other people's time.

I have nothing further to state on the topic, and recommend to 
others to take the same approach.  

Brendan.
