DCI OOB Protocol
Debug commands entered via the TRACE32 PowerView GUI are converted by TRACE32 into JTAG commands and wrapped into the DCI OOB protocol. TRACE32 sends these commands to the target system.
In the target system the commands are decoded by the OOB module and forwarded to the DCI bridge. The DCI bridge on the target side unwraps the DCI packets and passes the JTAG commands to the appropriate TAP/CPU. The communication between the target and the tool traverses the same path backwards.
Trace data can be exported through the DCI bridge/OOB module and are recorded by the CombiProbe.
