DLL Enable/Disable
DLL enable is required during power-up initialization
and upon returning to normal operation after having
disabled the DLL for the purpose of debug or evalua-

is enabled automatically.) Any time the DLL is enabled,
200 clock cycles with CKE HIGH must occur before a
READ command can be issued.
