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.
