User-Defined DIP Switch
Board reference SW1 is a eight-pin DIP switch. This switch is user-defined and
provides additional FPGA or HPS input control. When the switch is in the OFF
position, a logic 1 is selected. When the switch is in the ON position, a logic 0 is
selected. There are no board-specific functions for this switch.
Table 2–13 lists the user-defined DIP switch schematic signal names and their
corresponding Cyclone V SoC pin numbers.
User-Defined LEDs
Board references D1–D8 are eight user-defined LEDs. The status and debugging
signals are driven to the LEDs from the FPGA or HPS designs loaded into the
Cyclone V SoC. Driving a logic 0 on the I/O port turns the LED on while driving a
logic 1 turns the LED off. There are no board-specific functions for these LEDs.
Table 2–14 lists the general LED schematic signal names and their corresponding
Cyclone V SoC pin numbers.
