General User Input/Output
This section describes the user I/O interface to the FPGA including the push buttons,
user and status LEDs, LCD, and user DIP, rotary, and slide switches.
Table 2–11 lists
the component references and the manufacturing information.
Push Buttons
The board has eight push buttons for user-defined logic input. Each push-button
when pressed drives logic low and when released returns to driving logic high.
Table 2–12 summarizes the push buttons signal name and function.
