Five of the signals connect to both the JTAG pins on the Stratix II device
(U18) and the Stratix II device’s JTAG connector (J24). The JTAG signals
have special usage requirements. You cannot use J20 and J24 at the same
time.
Figure 2–7 below shows connections from the Mictor connector to the
Stratix II device. Figure 2–8 shows the pin-out for J20. Unless otherwise
noted, labels indicate Stratix II device pin numbers.
