10.2.1. Processor interfaces

System register access allows the processor to directly access certain debug registers. The external debug interface allows both external and self-hosted debug agents to access debug registers. See External debug interface.

Access to the debug registers is partitioned as follows:

Debug registers

This interface is System register based and memory-mapped. You can access the debug register map using the APB slave port. See External debug interface.

Performance monitor

This interface is System register based and memory-mapped. You can access the performance monitor registers using the APB slave port. See External debug interface.

Trace registers

This interface is memory-mapped. See External debug interface.
