Channel Segment Address Registers. For each of the 8 interleave ranges, they specify
the offset between the System Address and the Memory Address and the System
Address bits used for level 1 interleave, which should not be translated to Memory
Address bits. Memory Address is calculated from System Address and the contents of
these registers by the following algorithm:

Address bits used for level 1 interleave, which should not be translated to Memory
Address bits. Memory Address is calculated from System Address and the contents of
these registers by the following algorithm:
m[39:16] = SystemAddress[39:16] + (sign extend {Offset[23:0]});
m[15:6] = SystemAddress[15:6];
If (Removed[2]) {bit 8 removed};
If (Removed[1]) {bit 7 removed};
If (Removed[0]) {bit 6 removed};
MemoryAddress[36:6] = m[36:6];
m[15:6] = SystemAddress[15:6];
If (Removed[2]) {bit 8 removed};
If (Removed[1]) {bit 7 removed};
If (Removed[0]) {bit 6 removed};
MemoryAddress[36:6] = m[36:6];
The table below summarizes the combinations of removed bits and divide-by-3
operations for the various supported interleave configurations. All other combinations
are not supported.

Note:
If any of bits [8:6] are removed, the higher order bits are shifted down.
