In normal bidirectional operation, you 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.
