Hi All;
 

The SX family has some fuse bits that can be manipulated with the SYNC directive. According to the documentation, when this is activated it apparently routes all port input bits through a two stage flip flop toggled by the processor clock in order to isosync inputs to the clock....hunh?????

 

I have not messed with this "feature" yet as I can't understand the purpose of it.

 

Can anyone shed some light on this?

 

Cheers,
