AD2S1210 resolution when switching normal and configuration mode

In datasheet P21 "RES0, RES1 Inputs" that

When switching between normal mode and configuration mode, it is the responsibility of the user to ensure that the resolution set in the control register matches the resolution set by the RES0 and RES1 input pins. Failure to do so may result in incorrect data on the outputs, caused by the differences between the resolution settings.


Why config mode and normal mode must be match ?

So When different each mode, the type of AD2S1210's error randomly appears.

I understand that I must align the resolution. But  customers want to know why they must align its resolutions and what kind of mechanism it is.

Customers are strongly requesting this question.


Please help me.
Thank you.
