ASD0 is reserved at location C4

Hello,

I am working on a 2C50 which pins are connected to a TX_DAC. A TX_DATA pin is connected to C4. When I try to assign on this C4 pin, during the compilation an error occurs " ASD0 is reserved at location C4". People used to use this pin, what can I do?

Thank you for answers

    What kind of configuration device do you use for the FPGA? Check that the programming device setting in Quartus matches your board.

    If you share the pin C4 between the flash and your DAC, you must enable it as a general I/O in the 'dual purpose pins' tab of the device settings.
