Trace Connectors (X3, X4); Primary Trace-Connector (X3) - Fujitsu SK-MB9EF120-002 User Manual

5.3 Trace Connectors (X3, X4)

Much like the Debug-connector, this is also defined by ARM.
These connectors must not be used at the same time as the debug-connector.

5.3.1 Primary Trace-Connector (X3)

This can be used without X4, providing up an up to 16-bits trace-port.
