7.OPERATION
7.1. Deselect
The DESELECT function (/CS HIGH) prevents new commands from being executed by the Mobile DDR SDRAM. The Mobile DDR
SDRAM is effectively deselected. Operations already in progress are not affected.
7.2. No Operation
The NO OPERATION (NOP) command is used to instruct the selected DDR SDRAM to perform a NOP (/CS = LOW, / RAS = /CAS
= /WE = HIGH). This prevents unwanted commands from being registered during idle or wait states. Operations already in progress
are not affected.
