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. You can use the OE register 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, and the column and row interconnects.
the IOE in bidirectional configuration.
The Arria GX device IOE includes programmable delays that can be activated to
ensure input IOE register-to-logic array register transfers, input pin-to-logic array
register transfers, or output IOE register-to-pin transfers.
