Notes
1. For a burst length of two, A1-Ai selects the two-data-element block; A0 selects the first access within the block.
2. For a burst length of four, A2-Ai selects the four-data-element block; A0-A1 selects the first access within the block.
3. For a burst length of eight, A3-Ai selects the eight-data- element block; A0-A2 selects the first access with in the block.
4. Whenever a boundary of the block is reached within a given sequence above, the following access wraps within the block.
