Trigger Switch
The DE4 provides a 2-pin header (JP2) with one pin connected directly to the Stratix IV GX FPGA,
while the other pin connected to GND. The 2-pin header is intended to be used as a trigger switch
(not included in the DE4 kit package). It is placed in a location where the PCIe bracket is installed
which conveniently allows users to install a trigger switch to the 2-pin header as the DE4 is
connected to the PC through the PCIe slot shown in
Figure 2–25
. Users can incorporate the trigger
switch in their design as a reset or trigger function.
Table 2–24
shows the pin assignments of the
2-pin header.
