Reference Manual
Figure 2–4 illustrates the JTAG chain.
Each jumper shown in Figure 2–4 is located in the JTAG chain DIP switch (SW6) on
the back of the board. To connect a device or interface in the chain, you must set the
corresponding switch from the JTAG chain DIP switch (SW6). The interface in the
JTAG chain depends on the switch settings but the FPGAs and MAX II devices are
always in the JTAG chain.
