All XP IOB pins can enable a weak internal PULLUP bias to VCCO, a weak internal PULLDOWN to GND, or a weak internal KEEPER circuit that both pulls up to VCCO or pulls down to GND, based on the last driven pin voltage. The PULLTYPE attribute can be set to NONE, PULLUP, PULLDOWN, or KEEPER using the following syntax in the XDC file:
set_property PULLTYPE value [get_ports port_name]
