DDR2 Memory Controller External Data (continued)
On-die termination signals to external DDR2 SDRAM. These pins
are reserved for future use and should not be connected to the
DDR2 SDRAM.
Note: There are no on-die termination resistors implemented on
the DM647/DM648DSP die.

DDR2 Memory Controller byte-enable controls. Decoded from the
low-order address bits. The number of address bits or byte
enables used depends on the width of external memory. Byte-write
enables for most types of memory. Can be directly connected to
SDRAM read and write mask signal (SDQM).
DDR2 Memory Controller data strobe [3:0]
DDR2 Memory Controller data strobe [3:0] negative
DDR2 Memory Controller SDRAM row address strobe
DDR2 Memory Controller SDRAM write enable
