Mode Register Definition
Preliminary
The mode register must be loaded when all banks are idle, and the controller must wait
the specified time before initiating the subsequent operation. Violating either of these
requirements will result in unspecified operation.
Burst Length
Read and write accesses to the SDRAM are burst oriented, with the burst length being
programmable, as shown in Figure 4, "Mode Register Definition," on page 11. The burst
length determines the maximum number of column locations that can be accessed for a
given READ or WRITE command. Burst lengths of 1, 2, 4, or 8 locations are available for
both the sequential and the interleaved burst types.
Reserved states should not be used, as unknown operation or incompatibility with
future versions may result.
When a READ or WRITE command is issued, a block of columns equal to the burst
length is effectively selected. All accesses for that burst take place within this block,
meaning that the burst will wrap within the block if a boundary is reached. The block is
uniquely selected by A0–A8 when the burst length is set to two; by A2–A8 when the burst
length is set to four; and by A3–A8 when the burst length is set to eight.
