2.3.2 COM-AP

This is the external-side COM-AP component for ADIv5.2-compliant systems, such as Arm® CoreSight™ SoC-400.

This component provides access to a duplex COM Wire Interface (CWI) link for low-bandwidth communication. The COM-AP is used on the debugger side and recognized as a special access port by the debugger. It has Powerup and Reboot Request interfaces to request power for the internal side or to send a request to reboot the servicing agent.

This component uses a DAP bus. The following figure shows the port connections:
