The processor does not have an external coprocessor interface but it does implement two internal coprocessors, CP14 and CP15.
The CP15 coprocessor is also known as the system control coprocessor and is used to control and provide status information for the functions implemented in the processor. See Chapter 3 System Control Coprocessor for more information on the system control coprocessor.
The CP14 coprocessor is also known as the debug coprocessor and is used for various debug functions. See Chapter 12 Debug for more information on the debug coprocessor.
