BURST LENGTH
Read and write accesses to the DDR SDRAM are burst oriented, with the burst length being set and the burst order
as in Burst Definition. The burst length determines the maximum number of column locations that can be accessed for
a given READ or WRITE command. Burst lengths of 2, 4, or 8 locations are available for both the sequential and the
interleaved burst types.

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