Five of the signals connect directly to both the JTAG pins on the Cyclone
device (U60), and the Cyclone device’s JTAG connector (J24). The JTAG
signals have special usage requirements. You cannot use J24 and J25 at the
same time.
Figure 1–12 below shows connections from the Mictor connector to the
Cyclone device. Figure 1–13 shows the pin out for J25. Unless otherwise
noted, labels indicate Cyclone device pin numbers.
