MODE REGISTER SET
Figure 7
Mode Register Set Command
The Mode Register and Extended Mode Register are loaded via inputs A0 - A11 (see mode register descriptions
in
Chapter 2.2
). The MODE REGISTER SET command can only be issued when all banks are idle and no bursts
are in progress. A subsequent executable command cannot be issued until
t
MRD
is met.
