When using the IOE for DDR outputs, the two output registers are  
configured to clock two data paths from LEs on rising clock edges. These  
output registers are multiplexed by the clock to drive the output pin at a  
×2 rate. One output register clocks the first bit out on the clock high time,  
while the other output register clocks the second bit out on the clock low  
time. Figure 2–67 shows the IOE configured for DDR output. Figure 2–68  
shows the DDR output timing diagram.
