User Input-Output Components; User-Defined Pushbuttons - Intel Stratix 10 GX User Manual

4 Board Components
MAX V Reset Pushbutton
This pushbutton is the development board's Master Reset. This pushbuttton is
connected to the MAX V CPLD (
When this button is pressed, the MAX V CPLD initiates a reloading of the stored image
from flash memory using AvST configuration mode. The image that is reloaded
depends on the
CPU Reset Pushbutton
This pushbutton is the Nios II CPU Reset. This button is connected to a Intel Stratix 10
GX FPGA global signal input pin and can be used by Nios II implementations as a
dedicated CPU Reset button. This button is also connected to the MAX V CPLD so that
the FPGA device can be reset right after its configuration with AvST mode.

4.7 User Input-Output Components

This section describes the user I/O interface to the FPGA. The following I/O elements
are described:
•

User-defined pushbuttons

• User-defined DIP switches
• User-defined LEDs
• Character LCD
4.7.1 User-Defined Pushbuttons
The development kit includes 8 user-defined pushbuttons and 4 system pushbuttons
that allow you to interact with the Intel Stratix 10 GX FPGA. When you press and hold
down the pushbutton, the device pin is set to logic 0; when you release the
pushbutton, the device pin is set to logic 1. There is no board-specific function for
these general user pushbuttons.
The table below lists the pushbuttons, schematic signal names and their corresponding
Intel Stratix 10 GX FPGA device pin numbers.
