JTAG signals are available at:
- gender-inverted standard 6-pin JTAG header connector J2;
- B2B connector JM4.
JTAG Connector J2
The offset holes of header J2 allow a removable press fit of standard 0.100 inch header pins to connect flying leads without any soldering necessary.
JTAG signals are available on the dedicated header J2 through a JTAG programmer with flying leads as described in the table below.

JTAG connector J2.
To connect your computer to JTAG connector J2, you typically need
- a JTAG cable with standard 6-pin JTAG female header;
- a 2.54 mm pitch 1 × 6 pin gender changer header.
Some examples of JTAG cable set are listed in the table below.
JTAG cable | flying leads | software | gender changer |
|---|---|---|---|
Xilinx Platform Cable USB | included | Xilinx iMPACT | 1 × 6 pin |
Digilent XUP USB-JTAG Programming Cable | XUP Fly Wire Assembly | Xilinx iMPACT | 1 × 6 pin |
Digilent JTAG-USB Full Speed Module | included | Xilinx iMPACT | 1 × 6 pin |
| JTAG HS1 Programming Cable | not needed | Xilinx iMPACT Digilent Adept 2.0 | not needed |
| JTAG HS1 Programming Cable | not needed | Xilinx iMPACT Digilent Adept 2.0 | not needed |
Some examples of JTAG cable set.
Figure A below shows a standard 6-pin JTAG female header, in this case flying leads, with a gender changer header.
Figure B below shows how a JTAG cable, in this case a Xilinx Platform Cable USB with flying leads and gender changer, is connected to a TE0320.

The figure below shows a recommended set-up for TE0320 configuration and operation. The USB cable provides for power supply and data communication channel. The JTAG is ideal for quick configuration and effective debugging.
Recommended development set-up for TE0320.
JTAG lines at B2B connector JM4
JTAG signal lines are also available at B2B connector JM4 (pins 74, 76, 78 and 80). See the corresponding pin-out table for additional information on these signals.
