12.3. Debug register interface

You can access the processor debug register map using the APB slave port. The APB slave port conforms to the AMBA3 APBv3 standard as described in the AMBA 3 APB Protocol Specification. This is the only way to get full access to the processor debug capability. ARM recommends that if your system requires the processor to access its own debug registers, you choose a system interconnect structure that enables the processor to access the APB slave port by executing load and stores to an appropriate area of physical memory.
