Lpc2000

There are cases, when some data, like node address or hardware 
dependent constants, should be reprogrammed only several times during 
the whole system life.  And if there is a free flash, why do not use 
it, instead of an external EEPROM?  My question is just about such a 
case.
Except the flash programming examples, which I still need, maybe one 
can reference me to a document, where is a detailed description of 
commands, needed for it.
