My fitter does not allow me a pin associated with an asynchronous clock signal to be used as a standard I/O. Why?
If an asynchronous global clock is driven by an internal product term expression, the global clock pin associated with this clock is driven by the output macrocell. This excludes the use of the pin for any other function.
