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 2–8 lists the LED board references, names, and functional descriptions.

Description
D3 POWER — Blue LED. Illuminates when 5-V power is active.
D7 FAN FAN_LED
Amber LED. Illuminates when an over-temperature condition
occurs. This occurrence should automatically turn on the fan.
D8 USB USB_LED
Green LED. Illuminates when the MAX II CPLD System Controller
is actively configuring the FPGA using the embedded
USB-Blaster.
D9 ERROR CONFIG_ERR
Red LED. Illuminates when the MAX II CPLD System Controller
fails to configure the FPGA. Driven by the MAX II CPLD System
Controller.
D10 FACTORY FACTORY_IMAGE
Green LED. Illuminates when the factory image is successfully
loaded into the FPGA. Driven by the MAX II CPLD System
Controller.
D11 USER USER_IMAGE
Green LED. Illuminates when the user image is successfully
loaded into the FPGA. Driven by the MAX II CPLD System
Controller.
