The DLL must be enabled for normal operation. 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 evaluation. When the device exits self refresh mode, the DLL
is enabled automatically. Any time the DLL is enabled, 200 clock cycles with CKE HIGH
must occur before a READ command can be issued.
