EXTENDED MODE REGISTER SET (EMRS)
The Extended Mode Register controls functions beyond those controlled by the Mode Register; these additional func-
tions include DLL enable/disable, output driver strength selection(optional). These functions are controlled via the bits
shown below. The Extended Mode Register is programmed via the Mode Register Set command ( BA0=1 and BA1=0)
and will retain the stored information until it is programmed again or the device loses power.
The Extended Mode Register must be loaded when all banks are idle and no bursts are in progress, and the controller
must wait the specified time before initiating any subsequent operation. Violating either of these requirements will
result in unspecified operation.
