EXTSUPPLY no longer part of NRF_UICR_Type

[Youssif]

Hi

We're migrating our code from SDK14.2.0 to SDK15.0.0 and we can no longer see EXTSUPPLY as part of NRF_UICR_Type. Is there anywhere we can read about this change and what we need to do to our application to maintain same functionality? We could not find this in SDK15.0.0's migration guide nor in the softdevice S140 v6.0.0 migration document.

Our app used EXTSUPPLY to enable external circuitry to be supplied from the Vdd pin, and the value for the Vdd pin is set using REGOUT0 member.

We are using SDK15.0.0 and softdevice S140 v6.0.0 on an nRF52840 PDK.

Thanks

Youssif

The EXTSUPPLY register is deprecated and no longer needed to enable external circuitry.

Thanks for your quick response. So, just to confirm, all we have to do is set NRF_UICR->REGOUT0 to a new value (e.g. 0 to get 1.8V), reset the device, and the value will take effect?

Yes, that is correct.
