The SELF REFRESH command is initiated when CKE is LOW. The differential clock
should remain stable and meet
refresh mode. The procedure for exiting self refresh requires a sequence of commands.
First, the differential clock must be stable and meet
prior to CKE going back to HIGH. Once CKE is HIGH (
with three clock registrations), the DDR2 SDRAM must have NOP or DESELECT com-
mands issued for
ments is used to apply NOP or DESELECT commands for 200 clock cycles before
applying any other command.
