0
OFFSET.
This field defines the offset used in the rank interleave. This is a 2's
complement value.
3:0
RW
0
RANK.
This field defines which rank participates in WAY(n). If MC.CLOSEDPAGE=1, this
field defines the DRAM rank selected when MemoryAddress[7:6]=(n). If
MC.CLOSEDPAGE=0, this field defines which rank is selected when
MemoryAddress[13:12]=(n). (n) is the instantiation of the register. This field is
organized by physical rank. Bits [3:2] are the encoded DIMM ID(slot). Bits
[1:0] are the rank within that DIMM.
