Synopsis
Official Name: EraseFlash
BCALL Address: 8024
Erase a Flash sector (reset it to all FF's.)
Inputs
- A = Flash page to erase
- HL = address to erase
Outputs
- NZ if the sector could not be erased
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+.
