BQ27542-G1: How to reserve the capacitor?

Hi,Sir;
    We want to reserve the capacitor without change the SOC flow and the minimum voltage,

Is only need change the register "Reserve Cap-mAh" in the "Gas Gauge" page of the Data memory?

Any other register also need to change?

How to change?

And how to check the change is OK?

Need any learning after change the registers?

Thanks!
