5:3 rw 0x1 [1:0] - Indicates which remote ODT's must be
turned on during a write to rank 0. Each of the 2
ranks has a remote ODT (in the DRAM) which can
be turned on by setting the appropriate bit here.
Rank 0 is controlled by the LSB; Rank 1 is
controlled by bit next to the LSB.
For each rank, set its bit to 1 to enable its ODT.
[2]: If 1 then local ODT is enabled during writes to
rank 0.
