Cyclone IV I/O elements (IOEs) contain a bidirectional I/O buffer and five registers
for registering input, output, output-enable signals, and complete embedded
bidirectional single-data rate transfer. I/O pins support various single-ended and
differential I/O standards.
The IOE contains one input register, two output registers, and two output-enable (OE)
registers. The two output registers and two OE registers are used for DDR
applications. You can use input registers for fast setup times and output registers for
fast clock-to-output times. Additionally, you can use OE registers for fast
clock-to-output enable timing. You can use IOEs for input, output, or bidirectional
data paths.
