In normal bidirectional operation, the designer can use the input register
for input data requiring fast setup times. The input register can have its
own clock input and clock enable separate from the OE and output
registers. The output register can be used for data requiring fast clock-to-
output performance. The OE register is available for fast clock-to-output
enable timing. The OE and output register share the same clock source
and the same clock enable source from the local interconnect in the
associated LAB, dedicated I/O clocks, or the column and row
interconnects.
