9.3.1.10 ODA: Other Data Address
This location provides the offset to the Other Data Section. Writes to this register have
no effect.
9.3.1.11 RES1: Reserved 1
This location is reserved. Writes to this register have no effect.
9.3.2 Processor Data
This section contains three pieces of data:
• The S-spec/QDF of the part in ASCII format.
• (1) 2-bit field to declare if the part is a pre-production sample or a production unit.
• The system bus speed in BCD format
9.3.2.1 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.
Example: A processor with a QDF mark of QWFZ contains the following in field 0E-
13h: 20h, 20h, 51h, 57h, 46h, 5Ah. This data consists of two blanks at 0Eh and 0Fh
followed by the ASCII codes for QEU5 in locations 10 - 13h.
