IntelR 80960 RN I/O Processor Datasheet

Intel ® 80960RN I/O Processor
5.0 Device Identification on Reset
During the manufacturing process, values characterizing the i960 RM/RN I/O processor type and
stepping are programmed into memory-mapped registers. The i960 RM/RN I/O processor contains
two, read-only device ID MMRs. One holds the Processor Device ID (PDIDR MMR Location -
0000 1710H) and the other holds the i960 Core Processor Device ID (DEVICEID MMR Location -
FF00 8710H). During initialization, the DEVICEID is placed in g0.
The device identification values are compliant with the IEEE 1149.1 specification and Intel
standards. Table 30 describes the fields of the two Device IDs.
Table 30.
Note:
The value programmed into these registers varies with stepping. Refer to the Specification Update
for the correct value.
