3.4.52. Device Affinity Register

The TRCDEVAFF0 characteristics are:


Enables the ETM-R7 to determine which processor in the Cortex-R7 MPCore processor the component relates to.

Usage constraints

There are no usage constraints.


Available in all configurations.


See the register summary in Table 3.1 and Table 3.11.

Figure 3.59 shows the TRCDEVAFF0 bit assignments.

[31]-Indicates the register uses the new multiprocessor format. This is always 1.
[30]U bit

Multiprocessing Extensions:

Set to 0

Processor is part of a multiprocessor cluster.

[11:8]Cluster ID

Value read in CLUSTERID configuration pins. It identifies a Cortex-R7 processor in a system with more than one Cortex-R7 processor present.

[1:0]CPU ID

Indicates the processor number in the Cortex-R7 MPCore configuration:


Processor 0.


Processor 1.
