1. A method, comprising: at an implantable medical device comprising an implantable coil:

receiving, via the implantable coil, inductive power signals transmitted by an external coil excitation system associated with a secondary mode of operation of the implantable medical device to the implantable coil via an inductive link;

determining, based on the inductive power signals received at the implantable coil, that power is being transferred by the external coil excitation system via the inductive power signals; and

in response to the determining, switching the implantable medical device to the secondary mode of operation.
