DLL Enable / Disable
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 (upon exiting Self Refresh Mode, the DLL is
enable automatically). Any time the DLL is enabled, 200 clock cycles must occur before a READ command can be issued.
Output Drive Strength
The normal drive strength for all outputs is specified to be SSTL_2, Class II. M13S128168A also support a weak drive strength
option, intended for lighter load and/or point-to-point environments.
