2.3.1 External APBCOM

This is the external-side APBCOM component for ADIv6-compliant systems, such as Arm® CoreSight™ SoC-600.

The APBCOM component provides APB access to a duplex COM Wire Interface (CWI) link for low-bandwidth communication. This component is used on the debugger side and recognized as a CoreSight peripheral device 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 an APB bus. The following figure shows the port connections:
