Hi all,I am working on a video frame buffer which is using the cyclone 4E FPGA and the altera megafunction DDR2 SDRAM controller with ALTMENPHY. I am dealing with the streaming video data, thus I don't need the auto-refresh function in the DDR2 controller. is it possible to turn it off so that I may save some bandwidth? Thanks Daniel
