CycloneV (5CEBA2F23C7) is used. I want to use a configuration pin as a user pin. Pin number is not displayed in Pin Planner. Even if defined in the qsf file, a fitting error occurs. - CycloneV (5CEBA2F23C7) is used. I want to use a configuration pin as a user pin. Pin number is not displayed in Pin Planner.

Please refer to the Configuration user guide for information. https://www.intel.com/content/www/us/en/programmable/documentation/lro1432739743862.html We are going away from subject of the question.

Cyclone III (EP3C16F484C6N) could use the configuration pin (It was a dual-purpose pin) Can the CycloneV configuration ROM be used for NIOS? Replies: Re: CycloneV (5CEBA2F23C7) is used.

Hi Kato, Those pins are not dual-purpose pin check pin connection guidelines. So we can't use it as user pins. However, we pin DATA[5:15] as user pin. Go to Quartus II Assignments menu -> Device -> Device and Pin Options -> Dual-Purpose Pins window, choose the value "Use as regular I/O". Regards Anand Replies: Re: CycloneV (5CEBA2F23C7) is used.

The pin you want to use 1.AS_DATA0 / ASDO (AB4) 2.DCLK (V3) 3.AS_DATA1 (AB3) 4.nCSO (R4)
