Bus-hold circuitry is active only after configuration. When going into user mode, the
bus-hold circuit captures the value on the pin present at the end of configuration.
Each Stratix IV device I/O pin provides an optional programmable pull-up resistor
during user mode. If you enable this feature for an I/O pin, the pull-up resistor
(typically 25 K ) weakly holds the I/O to the V
Programmable pull-up resistors are only supported on user I/O pins and are not
supported on dedicated configuration pins, JTAG pins, or dedicated clock pins. If you
enable the programmable pull-up option, you cannot use the bus-hold feature.
When the optional DEV_OE signal drives low, all the I/O pins remain tri-stated even
with the programmable pull-up option enabled.
Stratix IV LVDS transmitters support programmable pre-emphasis to compensate for
the frequency dependent attenuation of the transmission line. The Quartus II software
allows four settings for programmable pre-emphasis.

The Stratix IV architecture supports the MultiVolt I/O interface feature that allows the
Stratix IV devices in all packages to interface with systems of different supply
voltages.
You can connect the VCCIO pins to a 1.2-, 1.5-, 1.8-, 2.5-, or 3.0-V power supply,
depending on the output requirements. The output levels are compatible with
systems of the same voltage as the power supply. (For example, when VCCIO pins are
connected to a 1.5-V power supply, the output levels are compatible with 1.5-V
systems.)
