All input signals to the IOE can be inverted at the IOE.
This signal connection is only allowed on dedicated DQ function pins.
This signal is for dedicated DQS function pins only.
The optional PCI clamp is only available on column I/O pins.

When using the IOE for DDR inputs, the two input registers clock double
rate input data on alternating edges. An input latch is also used in the IOE
for DDR input acquisition. The latch holds the data that is present during
the clock high times. This allows both bits of data to be synchronous with
the same clock edge (either rising or falling).
