 		 #109952 - For another Atmel
Responding to: ???'s previous message
Erik, Atmel is not very clear how the internal erasing/rewriting cycle works, so it is possible (and logical) it does not erase if the bytes to be changed are already/still blank - that would make the "walking write" essentially the same as on other devices.
For another Atmel ( the AT29C020 ) it is as I described. This, of course is no guarantee it is so for all bytewise flashes.

                           you are right, not byte, but autoerase            01/01/70 00:00
