Notes:
1. M13 (A13) is reserved for future use and must be programmed to “0.” A13 is not used in
2. Not all listed CL options are supported in any individual speed grade.
Accesses within a given burst may be programmed to be either sequential or interleaved.
The burst type is selected via bit M3, as shown in Figure 8. The ordering of accesses
within a burst is determined by the burst length, the burst type, and the starting column
address, as shown in Table 4 on page 21. DDR2 SDRAM supports 4-bit burst mode and 8-
bit burst mode only. For 8-bit burst mode, full, interleaved address ordering is
supported; however, sequential address ordering is nibble-based.
