Register Definition
Notes:
1. Whenever a boundary of the block is reached within a given sequence above, the fol-
lowing access wraps within the block.
2. For BL = 2, A1–Ai select the two-data-element block; A0 selects the first access within
the block.
3. For BL = 4, A2–Ai select the four-data-element block; A0–A1 select the first access
within the block.
4. For BL = 8, A3–Ai select the eight-data-element block; A0–A2 select the first access
within the block.
