Name
Number of bytes to skip from start of spare area
before last ECC sector data starts. The bytes will be
written with the value programmed in the spare_
area_marker register. This register could be
potentially used to preserve the bad block marker in
the spare area by marking it good. The default value is
zero which means no bytes will be skipped and last
ECC sector will start from the beginning of spare
area.
