DDR Registers
Each Stratix and Stratix GX IOE contains six registers and one latch. Two
registers and a latch are used for input, two registers are used for output,
and two registers are used for output enable control. The second output
enable register provides the write preamble for the DQS strobe in the
DDR external memory interfaces. This negative-edge output enable
register extends the high-impedance state of the pin by a half clock cycle
to provide the external memory's DQS preamble time specification.
