Table 2–15 lists the clock enable DIP switch component reference and manufacturing

information.

JTAG Chain Jumpers

The JTAG chain jumpers are provided to either remove or include devices in the

active JTAG chain. However, the Stratix IV E FPGA device is always in the JTAG

chain. Table 2–16 shows the jumper controls and its descriptions.

Table 2–17 lists the JTAG chain jumper component references and manufacturing

information.
