4.2.3.1 On-Board Debugger Connections
The table below shows the connections between the target and the debugger section. All the connections between the target and the debugger are tri-stated when the debugger is not using the interface. Hence, there are few contaminations of the signals, e.g., 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.
