These pins drive dedicated phase shift circuitry, which allows fine tune phase shift input clocks strobes properly align clock edges needed capture data. Optional data signal external memory interfacing modes. Optional data signal external memory interfacing modes. Optional data mask pins x16/x18 modes required when writing SDRAM DDR2 SDRAM devices. signal indicates that write valid. signal high, memory masks signals. Each group signals requires pin.
