Connect the EZTAG Download Cable to the parallel printer port
of your PC. This cable contains drivers to buffer the signals as
they are driven into the system.
Attach the flying leads to the EZTAG Download Cable (see
Figure 3.1). Leads attach to the inside row. The connector is
designed to fit only the correct way.
The power for the drivers is derived from the target system.
Connect the cable's VCC and GND wires to the corresponding
signals on the target board.
Next connect the JTAG TAP inputs. Connect TCK, TDI, TMS and
TDO to the target board. TRST is not supported by the XC9500
EZTAG Download Cable. If any of your JTAG parts have a TRST
pin, it should be connected to VCC.
