Figure 2–12 shows an example of an in-target system analyzer ISA-
Nios/T by First Silicon Solutions (FS2) Inc. connected to the Mictor
connector. For details, see www.fs2.com.

Five of the signals connect to both the JTAG pins on the FPGA (U62), and
the FPGA’s JTAG connector (J24). The JTAG signals have special usage
requirements. J25 and J24 cannot be used at the same time.
Figure 2–13 below shows connections from the Mictor connector to the
FPGA.
