2.1.1. Serial Wire or JTAG Debug Port

The Serial Wire or JTAG Debug Port (SWJ-DP) connects either a Serial Wire Debug or JTAG probe to the CoreSight SoC-400 debug system. This is the entry point into the debug infrastructure from the external debugger through the Debug Port (DP). Figure 2.1 shows the external connections on the SWJ-DP.

See Chapter 4 Debug Access Port.
