126.96.36.199. Error Detection CRC Settings
Turning on the Enable open drain on CRC error pin option allows the CRC ERROR pin to be set as an open-drain pin in some devices, which decouples the voltage level of the CRC ERROR pin from VCCIO voltage. You must connect a pull-up resistor to the CRC ERROR pin on your PCB if you turn on this option.
In addition to settings in the Device dialog box, you should verify settings in the Voltage page of the Settings dialog box.
