Mode Register Definition
3.1.1
Operating Mode
The normal operating mode is selected by issuing a Mode Register Set Command with bits A12-A7 set to zero,
and bits A6-A0 set to the desired values. Burst Length for Write bursts is fixed to one by issuing a Mode Register
Set command with bits A12-A10 and A8-A7 each set to zero, bit A9 set to one, and bits A0-A6 set to the desired
values.
All other combinations of values for A12-A7 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.
