2.2.5. Programmable Pull-Up Resistor

Intel® Agilex™ devices support programmable pull-up resistor on 1.2 V LVCMOS I/O. Each I/O pin provides an optional programmable pull-up resistor during user mode.

The programmable pull-up resistor feature is enabled by default on unused I/O for both 1.2 V and 1.5 V VCCIO_PIO. The pull-up resistor weakly holds the I/O to the VCCIO_PIO level.

If you enable the weak pull-up resistor, you cannot use the bus-hold feature.
