5.8.8. 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 Arria® V device supports programmable weak pull-up resistors only on user I/O pins.

For dedicated configuration pins, dedicated clock 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, dedicated clock pins, or JTAG pins in the Arria® V Pin Connection Guidelines.
