2.3.4 Internal APBCOM

The Internal APBCOM is the internal-side APBCOM component.

This component provides APB access to a duplex COM Wire Interface (CWI) link for low-bandwidth communication. It is used on the internal side and recognized as a CoreSight™ peripheral device by the servicing agent. It has a Power LPI interface to manage power and an IRQ interface to inform the servicing agent that an event occured.

This component uses an APB bus. The following figure shows the port connections:
