Each IOE contains its own control signal selection for the following
control signals: oe, ce_in, ce_out, aclr/preset, sclr/preset,
clk_in, and clk_out.
selection.
In normal bidirectional operation, the input register can be used 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 can be used for fast clock-to-output enable
timing. The OE and output register share the same clock source and the
same clock enable source from local interconnect in the associated LAB,
dedicated I/O clocks, and the column and row interconnects.
