I960 Datasheet, PDF (70/70 Pages) Intel Corporation – i960 RP/RD I/O PROCESSOR AT 3.3 VOLTS

i960^® Rx I/O Processor at 3.3 V
6.0 DEVICE IDENTIFICATION ON RESET
During the manufacturing process, values characterizing the i960 Rx I/O processor type and stepping are
programmed into the memory-mapped registers. The i960 Rx I/O processor contains two read-only device ID
MMRs. One holds the Processor Device ID (PDIDR - 0000 1710H) and the other holds the i960 Core
Processor Device ID (DEVICEID - FF00 8710H). During initialization, the PDIDR is placed in g0.
The device identification values are compliant with the IEEE 1149.1 specification and Intel standards. Table 32
describes the fields of the two Device IDs.
