3.7.3.4. Debug

The DSU supports both self-hosted and external debug. When you use self-hosted debug, you can use debug instructions to move the CPU into a debug state. When you use external debug, you can configure debug events to trigger the CPU to enter a debug state that is controlled by an external debugger.

The Arm* architecture allows for cores to be single, or multithreaded. A processing element (PE) performs a thread of execution. A single-threaded core has one PE, and a multi-threaded core has two or more PEs. Because the debugging system allows individual threads to be debugged, the term PE is used throughout this section.
