*PIN 2 can be detected by the white thick cable.

To connect your design to the JTAG-BOOSTER you need a single row berg

connector with a spacing of 2.54mm on your PCB. The names refer to the target:

Pin 7 is the target’s TDO pin and is connected to the JTAG-Booster’s TDI pin.

A 3.3V version of the JTAG-Booster is delivered for the AMD ElanSC520.

Do not connect the 3.3V JTAG-Booster to a 5V power supply. The JTAG-

Booster may be damaged.

Before you start the program, the JTAG-BOOSTER must be plugged to a parallel

interface of your PC and to the 8 pin JTAG connector on the target.
