The default drive strength setting is Full strength. The Programmable I/O Drive Strength mode is used to
change from the default I/O drive strength. Drive strength should be selected based on expected loading of
the memory bus. This table shows the four supported output drive-strength settings. The device returns to
the default drive strength mode when a power cycle has occurred. AC timing parameters may need to be
relaxed if I/O drive strength is not set to full.
