Command
Command
The normal operating mode is selected by issuing a LOAD MODE REGISTER command
with bits A[n:7] each set to zero, and bits A[6:0] set to the desired values.
All other combinations of values for A[n:7] are reserved for future use. Reserved states
should not be used because unknown operation or incompatibility with future versions
may result.
