Table 2–22 lists the backplane connector component reference and the manufacturing

information.

General User Input/Output

This section describes the user I/O interface to the FPGA. This section describes the

following I/O elements:

■ User-defined push buttons

■ User-defined DIP switch

■ User-defined LEDs

■ Character LCD

User-Defined Push Buttons

The development board includes four user-defined push buttons which allow you to

interact with the Stratix V GX device. When the push button is pressed and held

down, the device pin is set to logic 0; when the push button is released, the device pin

is set to logic 1. There is no board-specific function for these general user push

buttons.

Table 2–23 lists the user-defined push button schematic signal names and their

corresponding Stratix V GX device pin numbers.

Table 2–24 lists the user-defined push button component reference and the

manufacturing information.
