Operating Mode
The normal operating mode is selected by issuing a Mode Register Set Command with bits A7-A11 set to
zero, and bits A0-A6 set to the desired values. A DLL reset is initiated by issuing a Mode Register Set com-
mand with bits A7 and A
9
-A11 each set to zero, bit A8 set to one, and bits A0-A6 set to the desired values. A
Mode Register Set command issued to reset the DLL should always be followed by a Mode Register Set
command to select normal operating mode.
All other combinations of values for A7-A11 are reserved for future use and/or test modes. Test modes and
reserved states should not be used as unknown operation or incompatibility with future versions may result.
