The Configuration-Status LEDs

The EPM7128AE device is connected to four status LEDs that show the

configuration status of the board at a glance (see Figure 1–18). The user

can tell which configuration, if any, was loaded into the board at power-

on by looking at the LEDs (see Table 1 –8 ). If a new configuration was

downloaded into the Cyclone device via JTAG, then all of the LEDs will

turn off.
