Mode Register
1. MR0[16, 13, 7, 2] are reserved for future use and must be programmed to “0.”
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], as shown in Figure 51. 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 71 on page 113. 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.
