ARM Architecture Reference Manual ARMv7-A and ARMv7-R edition

Appendix A
Recommended External Debug Interface
This chapter describes the recommended external debug interface. It contains the following sections:
System integration signals on page AppxA-2
Recommended debug slave port on page AppxA-13.
Note
This recommended external debug interface specification is not part of the ARM architecture specification.
Implementers and users of the ARMv7 architecture must not consider this appendix as a requirement of the
architecture. It is included as an appendix to this manual only:
as reference material for users of ARM products that implement this interface
as an example of how an external debug interface might be implemented.
The inclusion of this appendix is no indication of whether any ARM products might, or might not,
implement this external debug interface. For details of the implemented external debug interface you must
always see the appropriate product documentation.
