The SoftDevice API uses SuperVisor Calls( SVCs) to exposes the functionality of the SoftDevice , this is stated here in the S130 SoftDevice Specification.

The SoftDevice is delivered as a precompiled binary and the SVCs are used to expose the SoftDevice functions without having any link-time dependencies between the application and the BLE protocol stack.
