DS90UB941AS-Q1: Discontinuous DSI data will cause lock loss ?

Hello Roy,

Well if you are trying to run the system in DSI reference clock mode but the DSI clock is discontinuous then you already have an issue there because the DSI clock is required to be continuous for DSI reference clock mode. If the clock is not continuous then it doesn't matter what your reg config is - the lock will not be stable

If you are using external REFCLK mode then the DSI clock does not need to be continuous but the reg config needs to be set to discontinuous mode for it to work correctly. There will likely be video issues but not necessarily lock problems in that configuration

Elec, 

DSI data is always discontinuous. There is no such thing as continuous mode on the DSI lanes unless you use LRTE which is an optional feature in DPHY (not supported)

Best Regards,

Casey
