Board Settings DIP switch
The board settings DIP switch controls various features specific to the board and the
MAX
II CPLD EPM2210 System Controller logic design. Table 2–11 shows the switch
controls and descriptions.
Table 2–12 lists the board settings DIP switch component reference and
manufacturing information.
JTAG Control DIP Switch
The JTAG control DIP switch is provided to either remove or include devices in the
active JTAG chain. However, the Stratix IV GX FPGA device is always in the JTAG
chain.
Table 2–13 shows the switch controls and its descriptions.
