The CRYPTOCELL subsystem is a hardware and software solution where software is delivered as libraries in Nordic device SDKs. Recommended usage of the CRYPTOCELL subsystem is to use the SDK library implementation available for the device. The CRYPTOCELL subsystem is documented for reference purpose only, please see section Disclaimer for more information.
To enable CRYPTOCELL, use register ENABLE. The device will not enter the System ON IDLE mode until CRYPTOCELL has been disabled, see POWER — Power control for more information. The Nordic SDK software library automatically controls enabling and disabling of the CRYPTOCELL subsystem as a part of its function calls.
