 Description:

Seven Programmable Attribute Map (PAM) registers are used to support these features.  Cacheability of these areas is controlled via the MTRR register in the core.
 - Two bits are used to specify memory attributes for each memory segment.  These bits apply to host accesses to the PAM areas.  These attributes are:
 - RE - Read Enable.  When RE=1, the host read accesses to the corresponding memory segment are claimed by the Uncore and directed to main memory.  Conversely, when RE=0, the host read accesses are directed to DMI.
 - WE - Write Enable.  When WE=1, the host write accesses to the corresponding memory segment are claimed by the Uncore and directed to main memory.  Conversely, when WE=0, the host read accesses are directed to DMI.
 - The RE and WE attributes permit a memory segment to be Read Only, Write Only, Read/Write or Disabled.  For example, if a memory segment has RE=1 and WE=0, the segment is Read Only.
