Extended Mode Register
The Extended Mode Register controls functions beyond those controlled by the Mode Register;
these additional functions include DLL enable/disable, bit A0; output drive strength selection, bit A1;
and QFC output enable/disable, bit A2 (NTC optional). These functions are controlled via the bit
settings shown in the Extended Mode Register Definition. The Extended Mode Register is
programmed via the Mode Register Set command (with BA0 = 1 and BA1 = 0) and retains 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 the controller must wait the specified time before
initiating any subsequent operation. Violating either of these requirements result in unspecified
operation.
