MSP430 accuracy if use the FLL to stable DCO

Any information about  accuracy for FLL to stable DCO for MSP430 MCU?

Lots of. What applies to a specific situation depends on how you use the FLL. So you'll have to compile it for your specific situation and application. It's way too much to compile it into a table or such.

The FLL is described in the users guide. This gives you information about systematical stability/performance. Then there's the question what your reference is. Crystal or REFO  (for those MSPs which have a REFO - you don't write which one you use and there are ~400 different MSPs). And how you use the clock system in your program (e.g. low power modes which deactivate the DCO have a huge influence). And then there are some device-specific errata which you can read in the device-specific errata sheet.
