10.2. About the Cortex-A9 debug interface

The Cortex-A9 processor implements the ARMv7 debug architecture as described in the ARM Architecture Reference Manual.

In addition, there are:

For more information, see Performance monitoring and Chapter 11 Performance Monitoring Unit.

The debug interface consists of:

  • a Baseline CP14 interface

  • an Extended CP14 interface

  • an external debug interface connected to the external debugger through a Debug Access Port (DAP).

Figure 10.2 shows the Cortex-A9 debug registers interface.
