How to change all inputs of AD9689?

DEARS.

This is an inquiry regarding the change of the AD9689's input-full-scale.
To change the input full scale, you need to change the register(0x1910).
Is there a sequence related to the change?


There is a sequence related to the Input Common Mode setting on page 30 of the data sheet.
In this case, there is a common mode buffer disconnect and voltage reference Off, but there is no procedure to turn it on again.
0x1910 is not displayed in the voltage reference change section on page 31.
The full scale doesn't seem to change by setting only the register(0x1910)


Please check how to change it.
Please explain in detail.

Thank you.
