Minimum delay from LAL following RDA to RDA of EMRS operation is CL+BL/2.
When DQ strobe mode is changed by EMRS, QS output is invalid for l
DLL switch in Extended Mode Register must be set to enable mode for normal operation.
DLL lock-on time is needed after initial EMRS operation. See Power Up Sequence.
