Notes:
1. For full-page accesses: y = 2,048
2. For BL = 2, A1–A9, A11 select the block-of-two burst; A0 selects the starting column within the block.
3. For BL = 4, A2–A9, A11 select the block-of-four burst; A0–A1 select the starting column within the block.
4. For BL = 8, A3–A9, A-11 select the block-of-eight burst; A0–A2 select the starting column within the block.
5. For a full-page burst, the full row is selected and A0–A9, A11 select the starting column.
6. Whenever a boundary of the block is reached within a given sequence above, the following access wraps within the block.
7. For BL = 1, A0–A9, A11 select the unique column to be accessed, and mode register bit M3 is ignored.
