Preliminary Information
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 51 on page 259 and are defined as follows:
I
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).

Notes:
1.
TDI is the input to bit 296, and TDO is driven from the output of bit 0. The entries listed as pin_E (where pin is an output or
bidirectional signal) are the enable bits.
2. Supported on low-power versions only.
