Cyclone III: access to the CRC32 register inside the project

Hi to All!

I'm trying to get access to the Pre-Computed CRC32, that is using in the error detection machine (Error Detection Mode is switched On).

I have found the reference to the cycloneiii_crcblock function in cyc3_ciii51013.pdf document, but I still cannot understand, how I can read the precomputed CRC32 with this function.

I'm using VHDL in my project. Please, give me some examples how I can solve my problem.

Thanks for your support

Regards

Vladimir
