Occasional ContributorDedicated Clock (CLK) pins
In my Altera Cyclone IV EP4CE10 Pin Information document, I see pins CLK1...7.
Can I use this pins as normal IO (mono or bidirezional) pins?

Hi,
Yes, DIFFCLK or CLK are dedicated clock pin can be used only as Input pin.
We can also cross check using quartus tool too, we expect fitter error for such a scenario.

CLa_RThanks for your ansewer.
If I read well, in the document you showed me, the pins labeled DIFFCLK [1..7], as in my case, can be used ONLY as input pins

Hi,
Yes _CLKOUTp or _CLKOUTn pins can be used as IO(mono or bidirectional) or clock.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
