and reserved states should not be used because
unknown operation or incompatibility with future ver-
sions may result.
Extended Mode Register
beyond those controlled by the mode register; these
additional functions are DLL enable/disable and out-
put drive strength. These functions are controlled via
the bits shown in Figure 7, Extended Mode Register
Definition Diagram, on page 11. The extended mode
register is programmed via the LOAD MODE REGIS-
TER command to the mode register (with BA0 = 1 and
BA1 = 0) and will retain the stored information until it
is programmed again or the device loses power. The
enabling of the DLL should always be followed by a
LOAD MODE REGISTER command to the mode regis-
ter (BA0/ BA1 both LOW) to reset the DLL.
all device 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 could result in unspecified opera-
tion.
