Debugging

Software debugging is via a 10-pin JTAG connection. It is possible to use a 10-pin to 20-pin

adapter to use standard 20-pin JTAG tools. The JTAG connector is not insulated, so for

debugging use the JTAG opto-insulation board (order code: AIJTAG/OPTO-1/A), a battery-

supplied notebook, or supply the board through an insulated AC source. The JTAG

connector is shown in

Figure 6.
