JTAG Mode: The FPGA will retain this configuration as long as power is applied to the board; the configuration is lost when the power is turned off. </p> <p><a href="http://lh6.ggpht.com/_lCR3unrmnM0/S3qRq_REh4I/AAAAAAAAAHg/6RGjC4L8O2Y/s1600-h/image13.png"><img style="display: inline" title="image" alt="image" src="http://lh6.ggpht.com/_lCR3unrmnM0/S3qO1EW_9xI/AAAAAAAAAHk/oSsbe_nVCys/image_thumb9.png?imgmax=800" width="440" height="204" /></a> <br /> <br />2.
