Deselect Command
The Deselect Command performs the same function as a No Operation Command. Deselect Command occurs when CS is brought
high, the RAS, CAS, and WE signals become don't cares.
Clock Suspend Mode
During normal access mode, CKE must be held high enabling the clock. When CKE is registered low while at least one of the
banks is active, Clock Suspend Mode is entered. The Clock Suspend mode deactivates the internal clock and suspends any
clocked operation that was currently being executed. There is a one clock delay between the registration of CKE low and the
time at which the SDRAM operation suspends. While in Clock Suspend mode, the SDRAM ignores any new commands that are
issued. The Clock Suspend mode is exited by bringing CKE high. There is a one clock cycle delay from when CKE returns high
to when Clock Suspend mode is exited.
