4.3.1 On-Board Debugger Connections
The following table provides the connection details between the target and the debugger section. All connections between the target and the debugger are tri-stated if the debugger is not actively using the interface.
For additional information on how to use the capabilities of the on-board debugger, refer to the Curiosity Nano+ Touch.
