- *
- *  NASID: (low NASID bit is 0) Memory and SHUB MMRs
- *   AS: 2-bit Address Space Identifier. Used only if low NASID bit is 0
- *     00: Local Resources and MMR space
- *           Top bit of NodeOffset

- *                  node id:

- *                        2: Local MMR Space
- *                        4: Local memory, regardless of local node id

- *     01: GET space.
- *     10: AMO space.
- *     11: Cacheable memory space.

- *  |0|  NASID   |AS| Nodeoffset   |
- *  +-+----------+--+--------------+
- *
- *  NASID: (low NASID bit is 1) TIO
- *   AS: 2-bit Chiplet Identifier
- *     00: TIO LB (Indicates TIO MMR access.)
- *     01: TIO ICE (indicates coretalk space access.)
- * 
- *   NodeOffset: top bit must be set.
- *
- *
- * Note that in both of the above address formats, the low
