LatticeECP3: In LatticeECP3, is it possible to change the Serdes mode from 8b/10b to 10b Serdes mode via the SCI on the fly when the data rates are same for both mode?
If all control registers bits setting are correct for both modes, it will work. To get the control registers bit setting information for each mode, you can use ORCAstra. You will have to apply reset after changing the mode.
