Table 12: Feature Addresses 80h: Programmable I/O Drive Strength

Note:

1.The programmable drive strength feature address is used to change 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 default drive strength is full strength. The device returns to the default drive strength mode when the device is power cycled. AC timing parameters may need to be relaxed if I/O drive strength is not set to full.
