2.1.1.5. Error Detection CRC Settings

The Error Detection CRC page specifies error detection cyclic redundancy check (CRC) use for the target device. When Enable error detection CRC is turned on, the device checks the validity of the programming data in the devices. Any changes made in the data while the device is in operation generates an error.

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.
