Enable open drain on CRC_ERROR pin

1,191 Views

I try to use the CRC_ERROR pin on a Cyclone IV device.

The functionality is however not clear.

According to the documentation this pin is open drain.

According to Quartus the open drain is selectable.

Question:

Does the selection:1/ Enable Error Detection CRC also enable the CRC_ERROR pin?

Or does the selection:2/ Enable open drain on CRC_ERROR pin enable this pin?

If selection 2/ is correct, then the text should read: Enable CRC_ERROR pin (open drain)

Thanks for any answer.
