SQNUM: S-Spec QDF Number

This location provides the S-Spec or QDF number of the processor. The S-spec/QDF field is six ASCII characters wide and is programmed with the same S-spec/QDF value as marked on the processor. If the value is less than six characters in length, leading spaces (20h) are programmed in this field. Writes to this register have no effect.

For example, a processor with a QDF mark of QWFZ contains the following in field 0D-12h: 20h, 20h, 51h, 57h, 46h, 5Ah. This data consists of two blanks at 0Dh and 0Eh followed by the ASCII codes for QEU5 in locations 0F - 12h.
