2.1. LEDs description.

CoLinkEx programmer have four LEDs for status indication

PWR – show status of programmer power supply

Connect – status of connection to USB

BUSY – this LED is ON if programmer in debug mode

ERROR – this LED is ON if any error is occur

3. JTAG interface

have a standard JTAG connector. The JTAG connector is a 20 way Insulation
CoLinkEx
Displacement Connector (IDC) keyed box header (2.54mm male) that mates with IDC
sockets mounted on a ribbon cable

CoLinkEx
Signal TYPE
3V3 output for supply target board from voltage
Power regulator of CoLinkEx. Voltage on this pin available,
if "3V3" jumper is closed
This pin is not connected in CoLinkEx
-
JTAG data input of target CPU. It is
recommended that this pin is pulled to a
output
defined state on the target board. Typically
connected to TDI of the target CPU.
JTAG mode set input of target CPU. This pin
should be pulled up on the target. Typically
output
connected to TMS of the target CPU
JTAG clock signal to target CPU. It is
recommended that this pin is pulled to a
output
defined state of the target board. Typically
connected to TCK of the target CPU
JTAG data output from target CPU. Typically
Input
connected to TDO of the target CPU.
Target CPU reset signal. Typically connected
to the RESET pin of the target CPU, which is
output
typically called "nRST", "nRESET" or "RESET".
This pin can be used to supply power to the
target hardware.
Power
"3V3" jumper is closed
These pins connected to GND in CoLinkEx.
They should also be connected to GND in the
Ground
target system
