2.4.1
NO OPERATION (NOP)
Figure 6
No Operation Command
The NO OPERATION (NOP) command is used to
perform a NOP to a Mobile-RAM which is selected (CS
= LOW). This prevents unwanted commands from
being registered during idle states. Operations already
in progress are not affected.
2.4.2
The DESELECT function (CS = HIGH) prevents new commands from being executed by the
Mobile-RAM
. The
Mobile-RAM
is effectively deselected. Operations already in progress are not affected.
