The table below shows the connections between the target and the debugger section. All connections between the target and the debugger are tri-stated as long as the debugger is not actively using the interface. Hence, since there are little contaminations of the signals, the pins can be configured to anything the user wants.
For further information on how to use the capabilities of the on-board debugger, see On-Board Debugger Overview.
