2 Access Port v1 Adapter

Use the css600_apv1adapter to connect a legacy Access Port (AP) with a DAP Internal (DAPBus) slave interface into an CoreSight™ Architecture v3 system.

The css600_apv1adapter:

  • Maps the legacy AP registers into the Arm® CoreSight™ Architecture Specification v3.0 APB4 memory map.
  • Provides ID registers that allow a debugger to identify the combination as a mapped legacy Access Port.
  • Provides integration registers that allow a debugger to check connectivity of the DP Abort signal.

The following figure shows the external connections on the Access Port v1 Adapter.
