3.5 Target Power
The Tracelink is capable of generating 2V, 3V, or 5V directly to the TVCC pin of the
debug header. This can be used to power target microprocessors requiring up to
500mA of current without the need for a separate power supply.
To enable this feature, a jumper needs to be installed onto option J2, which can be
accessed by flipping open the plastic case. This jumper is NOT installed by default.
