5.5.2.3. Weak 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.

The Intel® Arria® 10 device supports programmable weak pull-up resistors only on user I/O pins but not on dedicated configuration pins, dedicated clock pins, or JTAG pins .

If you enable this option, you cannot use the bus-hold feature.
