Figure 21-16. Preference Editor
After all of the pin attributes have been entered, close the Preference Editor, scroll down the right window, and dou-
ble click on Generate Bitstream Data (see Figure 21-17). Once the bitstream has been generated, go to the Pro-
gramming Procedure section of this document.

Design Notes
The following tips will help insure first pass success when using LatticeECP/EC devices with SPI Serial Flash.
The PROGRAMN pin can be left open, wired to a button, microprocessor, etc. The PROGRAMN pin should be high
at power-up, do not tie this pin to a pull-down resistor. There is a weak pull-up on this pin, but if needed, add an
external 10K ohm pull-up resistor.
