How to read reset reason on nRF54H20 using nrfx API?

[lammobile]

Hi Nordic team,

I am working with the nRF54H20 and would like to programmatically read the reset reason after startup.

The product specification lists the following reset sources for the nRF54H20 on Figure 71: Reset sources

Which API or register should I use to read the reset reason on the nRF54H20? (e.g., nrfx_reset_reason_get() or nrf_reset_resetreas_get(NRF_RESET)?)

Thanks,
