https://devzone.nordicsemi.com/f/nordic-q-a/116770/how-to-enable-disable-the-cc312-accelerator-on-nrf5340-for-encryptionI am planning to perform encryption using the CC312 accelerator on the nRF5340. I would like to evaluate the power consumption when using the accelerator. My approach is to enable and disable the accelerator while performing encryption.
