This section provides details on the processor's ROM table.
The Cortex-A72 processor includes a ROM table that complies with the ARM® CoreSight™ Architecture Specification. This table contains a list of components such as processor debug units, processor Cross Trigger Interfaces (CTIs), processor Performance Monitoring Units (PMUs) and processor Embedded Trace Macrocells (ETMs). Debuggers can use the ROM table to determine which components are implemented inside the processor.
If a component is not included in your configuration of the processor, the corresponding debug APB ROM table entry is still present but the component is marked as not present.
