i960® Rx I/O Processor at 3.3 V

ADVANCE INFORMATION

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.

NOTE:

Values programmed into this register vary with stepping. Refer to the

i960® Rx I/O Processor Specifi-

cation Update (272918) for the correct value.
