Figure 5 - Target Connector Pin-out
Please note the concept with the target voltage sense signal. This signal is used by the level
converters on the CC Debugger to handle different voltage levels on the target board and the
debugger. Pin 2 on the target connector must be connected to Vdd on the target board.

Alternatively, it is possible to power the target by connecting pin 9 to Vdd on the target. In that case,
the CC Debugger will supply 3.3V to the target.
