I/O Element
An IOE contains a bidirectional I/O buffer and a register that can be used
either as an input register for external data that requires a fast setup time,
or as an output register for data that requires fast clock-to-output
performance. In some cases, using an LE register for an input register will
result in a faster setup time than using an IOE register. IOEs can be used
as input, output, or bidirectional pins. For bidirectional registered I/O
implementation, the output register should be in the IOE, and the data
input and output enable registers should be LE registers placed adjacent
to the bidirectional pin. The Altera Compiler uses the programmable
inversion option to invert signals from the row and column interconnect
automatically where appropriate.
