1. DO n (or x or b or g) = data-out from column n (or column x or column b or column g).
2. BL = 2, BL = 4, or BL = 8 (if BL = 4 or BL = 8, the following burst interrupts the previous).
3. n', x', b', or g' indicate the next data-out following DO n, DO x, DO b, or DO g, respectively.
4. READs are to an active row in any bank.
