Operating Mode
The normal operating mode is selected by issuing a Mode Register Set Command with bits A7-A12 to zero, and bits A0-A6 set
to the desired values. A DLL reset is initiated by issuing a Mode Register Set command with bits A7 and A9-A12 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-A12 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.
