Reference Manual
Setup Elements
The development board includes several different kinds of setup elements. This
section describes the following setup elements:
Board settings DIP switch
JTAG chain header switch
PCI Express control DIP switch
CPU reset push button
MAX II reset push button
Configuration push button
Image select push button
f For more information about the default settings of the DIP switches, refer to the
Arria V GT FPGA Development Kit User Guide.
Board Settings DIP Switch
The board settings DIP switch (SW5) controls various features specific to the board
and the MAX
II CPLD EPM2210 System Controller logic design. Table 28 lists the
switch controls and descriptions.
JTAG Settings DIP Switch
The JTAG settings DIP switch (SW6) either remove or include devices in the active
JTAG chain. However, the Arria V GT FPGAs and MAX
II CPLD EPM2210 System
Controller are always in the JTAG chain. Table 29 lists the switch controls and its
descriptions.
