f For more information on the following topics, refer to the respective documents:

■ Board Update Portal and PFL Design, refer to the Stratix V GX FPGA Development

Kit User Guide.

■ PFL megafunction, refer to AN 386: Using the Parallel Flash Loader with the Quartus

II Software.

Status Elements

The development board includes board-specific status LEDs and switches for

enabling and configuring various features on the board, as well as a 16 character × 2

line LCD for displaying board power and temperature measurements. This section

describes these status elements.

Status LEDs

Surface mount LEDs indicate the various status of the board. A logic 0 is driven on the

I/O port to turn the LED on while a logic 1 is driven to turn the LED off.

Table 2–10 lists the LED board references, names, and functional descriptions.
