nRF52840 regulator configuration

Hello

I have just started development for the nRF52480 preview development kit.

I am powering the dev kit through USB on J2 (with power switch set to VDD).

I want to power peripherals with 3.3V so I am trying to write configuration for the REG0.

From what I can see from the OPS this requires changing EXTSUPPLY and REGOUT0 in the UICR registers, as well as DCDCEN0 in the POWER registers.

I have trouble finding any information on how to do this. I have found one function in the nrf_soc.h for the softdevice I might be able to use for enabling DC/DC converter but otherwise nothing.

For reference I am using SES for development.
