Reference Manual
Table 222 lists the HSMC user-defined LED schematic signal names and their
corresponding Cyclone IV GX pin numbers.
Table 223 lists the HSMC user-defined LED component reference and the
manufacturing information.
User-Defined DIP Switch
Board reference SW2 is an 8-pin DIP switch. The switch is user-defined, and is
provided for additional FPGA input control. There is no board-specific function for
this switch.
Table 224 lists the user-defined DIP switch schematic signal names and their
corresponding Cyclone IV GX pin numbers.
