Erase a Flash sector (reset it to all FF's.)
Inputs

Destroys
- AF
Comments
Flash must be write enabled first.
Note that this will erase an entire sector of Flash, which is usually 64k. It is physically impossible to erase a smaller area, due to the internal structure of the Flash chip used in the 83+.
