MASK 
Mask of Intel ME SEG. Space must be power of 2 aligned. Field indicates 
which bits must match the BASE in order to be inside the Intel ME range.

ENABLE 
Enable for Intel ME SEG. When enabled, all core access to Intel ME SEG 
space is aborted.

LIMIT
DRAM rule top limit address. Must be strictly greater than previous rule, 
even if this rule is disabled, unless this rule and all following rules are 
disabled. Lower limit is the previous rule (or 0 if it is first rule). This field is 
compared against MA[39:26] in the memory address map.

MODE
DRAM rule interleave mode. If a DRAM_RULE hits a 3 bit number is used to 
index into the corresponding interleave_list to determine which package 
the DRAM belongs to. This mode selects how that number is computed. 
00 = Address bits {8,7,6}. 
01 = Address bits {8,7,6} XORed with {18,17,16}. 
10 = Address bit {6}, MOD3(Address[39..6]). (Note 6 is the high order bit) 
11 = Reserved.

RW
0
ENABLE
Enable for DRAM rule. If Enabled Range between this rule and previous rule 
is Directed to HOME channel (unless overridden by other dedicated address 
range registers). If disabled, all accesses in this range are directed in MMIO 
to the IIH.
