Device Identification Register (DIR). The DIR is a 32-bit Test Data
register selected during the execution of the IDCODE
instruction. The fields of the DIR and their values are shown in
Table 46 and are defined as follows:
Table 46. Device Identification Register
Version Code
Version Code—This 4-bit field is incremented by AMD
manufacturing for each major revision of silicon.
Part Number—This 16-bit field identifies the specific
processor model.
Manufacturer—This 11-bit field identifies the manufacturer
of the component (AMD).
LSB—The least significant bit (LSB) of the DIR is always 1,
as specified by the IEEE 1149.1 standard.
