BQ34110: Data Flash setting for multi cell application

Should we set data flash parameters with the value per one cell although it is multi cell application?

For example, in 2 cells case,

Should we set 3000 to Fixed EDV0 register, but not 6000? 

Is it OK that Charge voltage is 4200, but not 8400?

And should we change Flash Update OK register to 5600?

Best Regards,
