Note:
starting location within the block. The programmed burst length applies to both READ
and WRITE bursts.
Accesses within a given burst may be programmed to either a sequential or an inter-
leaved order. The burst type is selected via MR0[3] (see Figure 53 (page 132)). The
ordering of accesses within a burst is determined by the burst length, the burst type,
and the starting column address. DDR3 only supports 4-bit burst chop and 8-bit burst
access modes. Full interleave address ordering is supported for READs, while WRITEs
are restricted to nibble (BC4) or word (BL8) boundaries.
1. MR0[16, 13, 7, 2] are reserved for future use and must be programmed to 0.
