SAMPROD: Sample/Production

This location contains the sample/production field, which is a two-bit field and is LSB aligned. All Q-spec material will use a value of 00b. All S-spec material will use a value of 01b. All other values are reserved. Writes to this register have no effect.

For example, a processor with a Qxxx mark (engineering sample) will have offset 13h set to 00h. A processor with an Sxxxx mark (production unit) will use 01h at offset 13h.
