General Purpose LEDs

(See Appendix B, Figure 18)
The LEDs provided on the LatticeECP3 Versa Evaluation Board are connected to general purpose FPGA I/Os.
These LEDs provide status for user designs and must be included in the design. The LEDs illuminate when the
FPGA output is driven LOW. Table 6 shows the LED and associated FPGA pins. These pins are within an I/O bank
connected to 3.3V and the user should program these to be LVCMOS33 type outputs in the design.
