5.6.9. Pull-up Resistor

Each I/O pin provides an optional programmable pull-up resistor during user mode. The pull-up resistor, typically 25 kΩ, weakly holds the I/O to the VCCIO level. If you enable this option, you cannot use the bus-hold feature.

The Stratix® V device supports programmable pull-up resistors only on user I/O pins.

For dedicated configuration pins or JTAG pins with internal pull-up resistors, these resistor values are not programmable. You can find more information related to the internal pull-up values for dedicated configuration pins or JTAG pins in the Stratix® V Pin Connection Guidelines.
