Table 2–12 lists the board-specific LEDs component references and manufacturing
information.
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
■ Reset configuration push-button switches
Board Settings DIP Switch
The board settings DIP switch (SW4) controls various features specific to the board
and the MAX
II CPLD EPM2210 System Controller logic design. Table 2–13 shows the
switch controls and descriptions.
