A UART receiver would be expected to oversample the input and synchronize on a start bit. I can't detect this in your code.

what do you suggest?

Using a divided ("ripple") clock has the disadvantage of causing timing conflicts when transfering the UART output to other design parts. The synchronous clock enable method would be preferred.

in my code....is there a problem with synchronisation?

thanx FvM.
