When using the IOE for DDR outputs, the two output registers are
configured to clock two data paths from ALMs 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.
