17.3.1.2 Device Information Capability Register (DICAR)

The DICAR, shown in Figure 17-4, identifies the revision level of the device. The value is

assigned and managed by the vendor specified in DIDCAR[DVI]. DICAR represents a copy of the

device’s system version register (SVR).

Table 17-8 describes the field of the DICAR.

17.3.1.3 Assembly Identity Capability Register (AIDCAR)

AIDCAR, shown in Figure 17-5, provides information regarding the type of assembly or

subsystem being used as well as the vendor who manufactured it.

Table 17-9 describes the fields of the AIDCAR.

Assembly identity field. The assembly field uniquely identifies the type of assembly or subsystem from the

vendor specified in the assembly vendor identity field. The value of the assembly identity field by default is

all zeros but may be assigned by a boot ROM device.

Assembly vendor identity field. The assembly vendor identity field identifies the vendor that manufactured the

assembly or subsystem. A value for the assembly vendor identity field is uniquely assigned to an assembly

vendor by the registration authority of the RapidIO Trade Association. By default, this value is all zeros but

may be assigned by a boot ROM device.
