7.4.3.6.1 PPN: Processor Part Number
This location contains seven ASCII characters reflecting the Intel part number for the
processor. This information is typically marked on the outside of the processor. If the
part number is less than 7 characters, a leading space is inserted into the value. The
part number should match the information found in the marking specification found in
Section 3. Writes to this register have no effect.
Example: A processor with a part number of 80565KH will have the following at offset
38 - 3Eh: 38h, 30h, 35h, 36h, 35h, 4Bh, 48h.
