Hi,

I have a query regarding the 16c87x devices that doesnt seem to be covered
(although I usually havent checked enough) in the data sheet regarding the
program flash.....

I was thinking about writing non-volatile to the program flash while the main
code is still running ( I need more than the 256x8 on board data E^2). This way,
I can get around having an external non-volatile data store and some other
problems, too. What I dont know is whether the program flash is "sectored", like
most other flash devices. I have to assume that :
   It is byte-sectored (if so, my evil master plan will succeed) and so I can
   plainly write to individual bytes without having to do a read->modify->write
   like most sectored flash/having the whole sector flapping around during the
   write cycle.
   You can write to the program flash while still accessing the program code
   with no ill effects.
   I run the risk of being able to overwrite my program code quite easily.
   I contend with only 1000 writes to these byte-sectored locations.

Has anyone done this already and found it to be reliable?

Regards,

Dan
