Features
7.4.3.2 Processor Data
This section contains two pieces of data:
• The S-spec 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 SNUM: S-Spec Number
This location provides the S-SPec number of the processor. The S-spec field is six ASCII
characters wide and is programmed with the same S-spec 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 S-Spec mark of SLA67 contains the following in field 0E-
13h: 20h, 53h, 4Ch, 41h, 36h, 37h. This data consists of one blank at 0Eh followed by
the ASCII codes for SLA67 in locations 0F - 13h.
