2.6. Access ports

An access port provides the interface between the debug port interface and one or more debug components present within the system. There are two kinds of access port supplied with this DAP:

All access ports follow a base standard for identification, and debuggers must be able to recognize and ignore access ports that they do not support. The connection method does not depend on the type of debug port used and the type of access port being accessed.

For more information on access ports and recommend debugger interaction with access ports, see the ARM Debug Interface v5 Architecture Specification and the ARM Debug Interface v5.1 Architecture Supplement.
