* NOTE: The SDRAM controller is capable of running at lower frequencies than some memory types support. When selecting a memory device for use with this controller, you should take into account the clock requirements for the memory along with the supported frequencies for the SDRAM controller and the resulting system frequency SDCLK = fsys/2.
