8.1.1.3 Target power supply
8.1.2
J-Link / J-Trace (UM08001)
Pin 19 of the connector can be used to supply power to the target hardware. Supply
voltage is 5V, max. current is 300mA. The output current is monitored and protected
against overload and short-circuit.
Power can be controlled via the J-Link commander. The following commands are
available to control power:

The J-Link and J-Trace JTAG connector is also com-
patible to ARM’s Serial Wire Debug (SWD).
The following table lists the J-Link / J-Trace SWD
pinout.

TYPE
This is the target reference voltage. It is used to check if
the target has power, to create the logic-level reference for
the input comparators and to control the output logic levels
to the target. It is normally fed from Vdd of the target board
and must not have a series resistor.
This pin is not connected in J-Link.
This pin is not used by J-Link. If the device may also be
accessed via JTAG, this pin may be connected to nTRST,
otherwise leave open.
This pin is not used by J-Link. If the device may also be
accessed via JTAG, this pin may be connected to TDI, other-
wise leave open.
Single bi-directional data pin. A pull-up resistor is required.
ARM recommends 100 kOhms.
Clock signal to target CPU.
It is recommended that this pin is pulled to a defined state
on the target board. Typically connected to TCK of target
CPU.
This pin is not used by J-Link when operating in SWD mode.
If the device may also be accessed via JTAG, this pin may
be connected to RTCK, otherwise leave open.
Serial Wire Output trace port. (Optional, not required for
SWD communication.)
Switch target power on
Switch target power off
Set target power supply default to "on"
Set target power supply default to "off"
