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 an input on the JTAG-Booster’s side.
The 3.3V version of the JTAG-Booster (FS part number 285) is delivered
together with this package. Don’t use the 5V version of the JTAG-Booster (FS
part number 227) with a 3.3V target. Don’t apply 5V to the 3.3V version of the
JTAG-Booster!
Your target must be able to power the JTAG-Booster, it draws about 100mA.
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.
