DLL Turn Off  Active LOW. Connecting this pin to ground turns off the DLL inside the device. The timing
in the DLL turned off operation differs from those listed in this data sheet. For normal operation, this pin
must be pulled HIGH through 10 K or less pull up resistor. The device behaves in DDR I mode when
the DLL is turned off. In this mode, operate the device at a frequency of up to 167 MHz with DDR I timing.
