Using DSTREAM-XT
2. Connect the debug cable to the target.
When connecting the debug cable to the target system, to guard against ground
potential variation, ensure that one of the GND pins of the debug connector
makes contact first. This ensures that all signal levels are correctly interpreted
as they connect. For pin details, see

Hot-plugging: disconnecting
When unplugging the debug connector, you must be aware that:
• If you are using a Return Test Clock (RTCK) system, make sure that no communication is taking
place between the system and the DSTREAM-XT system. Otherwise, if the DSTREAM-XT
system is waiting for a return clock, it might lock up.
• If you are not using an RTCK system, the debug software can handle this situation. However,
you must perform a Test Access Port (TAP) reset using the debugger when you next connect
the DSTREAM-XT system to a target. For more information on TAP resets, see
