nPM1300 Supply Vsys from battery even when Vbus is present

Hi,

We are currently in the process of evaluating the nPM1300 PMIC for our project and I would like to know if there is a way to supply Vsys using the battery even when Vbus is detected. The previous PMIC we used from TI (BQ25155a) allows us to do this via register configuration. However, I could not find any register settings in the PMIC that would enable this option for us.

Thanks,

The idea is to use the "USB 2.0 selective suspend" feature (PS chapter 6.1.4) in VBUSIN->VBUSSUSPEND register.
