Hi all I bought recently a Chinese development board for MaxII epm1270t144c5n (Mars-1270-Pro CoreBoard). There is on the board a crystal oscillator. I don't understand why output signal of oscillator is sent to a CPLD IO (IO 127) instead of GLCK input ?

Hi ,

I do not have that idea the logic behing the connection as the board is not from the intel . I am kindly requesting to contact to the Board vendor
