17.3.1 Architectural Registers

Following are the architectural registers of the RapidIO module. For additional details of these

registers, refer to the Parallel RapidIO Interconnect Specification.

17.3.1.1 Device Identity Capability Register (DIDCAR)

The DIDCAR is a read-only register that provides information regarding the type of device being

used as well as the vendor who manufactured it. Figure 17-3 describes the DIDCAR.

Table 17-7 describes the fields of the DIDCAR.

Description

0–15

Device identity field. Uniquely identifies the type of device from the vendor specified in the device

vendor identity field. The values of the device identity field are assigned and managed by the vendor.

0x0002—MPC8540

16–31

DVI

Device vendor identity field. Identifies the vendor that manufactured the device. A value is uniquely

assigned to a device vendor by the registration authority of the RapidIO Trade Association.
