The cell attributes is a bit field. The lowest 6 bits of these attributes represent the size of the circle of minimal radius centered at the center of this cell's bounding box that contains every OBJ (or opaque pixel) in the cell. This is divided by 4 and rounded up, with a maximum value representing a radius of 252 pixels. Bit 8 indicates if the cell uses H flip, bit 9 indicates if the cell uses V flip, bit 10 indicates if the cell uses both H and V flip, and bit 11 indicates if the cell has bounding box information.

A cell bank may wish to store additional data. This can be placed inside a user extended attributes block in the {{{CEBK}}} block. When present, it takes the form of a sequence of blocks (fully contained within the {{{CEBK}}} block) that take on the same structure as the containing blocks. There is no field indicating the number of blocks, however. The NCER format defines the following block here:

||Offset||Type||Meaning

| 0x00 | u16 | Number of cells

| 0x02 | u16 | Number of attributes per cell (always 1)

| 0x04 | void* | Offset to attribute array relative to this struct

The attribute array consists of one pointer per each cell in the bank. These point to the extended attribute data, which is a single u32 per each cell.
