Accessing CRC_ERROR circuitry in user logic

Hello, We plan to use the CRC_ERROR function of the Stratix II device, but I'm having a hard time to understand from the handbook and AN357 how I can access the block from user logic. What I'd ...

You're going to have to use the CRC_ERROR pin, but once you bring it back into the fabric via the bidir, you can do whatever you want with it -- including routing it to another output pin.
