7.4.3.1.10 ODA: Other Data Address
This location provides the offset to the Other Data Section. Writes to this register have
no effect.
7.4.3.1.11 RES1: Reserved 1
This locations are reserved. Writes to this register have no effect.
7.4.3.1.12 HCKS: Header Checksum
This location provides the checksum of the Header Section. Writes to this register have
no effect.
7.4.3.2 Processor Data
This section contains two 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
7.4.3.2.1 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 QEU5 contains the following in field 0E-13h:
20, 20, 51, 45, 55, 35h. This data consists of two blanks at 0Eh and 0Fh followed by
the ASCII codes for QEU5 in locations 10 - 13h.
