The following figure shows the debug host interfaces that are connected to the DPC.
There are four debug host interfaces. The hosts establish a packet protocol with the DPC. To create the response packet, the DPC writes to system resources via the DPC interconnect switch.
Note: The interconnect interfaces are
shown in the Interconnect Switch Diagrams section. The TPIU I/O
connections are shown in the Data Flow Diagrams
section.
