5.8.1. User-Defined Push Buttons
The development board includes 8 user-defined push buttons and 4 system push buttons that allow you to interact with the Intel® Arria® 10 GX FPGA device. When you press and hold down the push button, the device pin is set to logic 0; when you release the push button, the device pin is set to logic 1. There is no board-specific function for these general user push buttons.
The table below lists the push buttons, schematic signal names and their corresponding Intel® Arria® 10 GX FPGA device pin numbers.
Board Reference | Schematic Signal Name | Description | Arria 10 Device Pin Number |
