Woah, haven't heard of that one !  The Philips example (in the files
area) to emulate Eeprom using flash has the potential to do many many
writes (marching onwards through the flash) without an erase. Where did
you find out that information ? Certainly the Philips program should
have a re-programming counter if this is indeed the case. Can
phillips_apps (Robert) confirm ?
I haven't experienced any issues so far with many reprograms without
erase on the lab units. (Field units at present would typically not
experience many changes).

Cheers,
Bruce
