Abstract
In one embodiment, a method, of operating an implantable medical device, comprises: (i) operating reset logic within the implantable medical device that is independently operable from a processor of the implantable medical device after the implantable medical device is implanted within a patient, wherein the processor is adapted for central control of the implantable medical device; (ii) operating a magnetic field sensor in the implantable medical device; (iii) generating digital data using, at least, the magnetic field sensor; (iv) detecting, by the reset logic, a digital key in the digital data; (v) in response to (iv), asserting a reset signal on a pin of the processor by the reset logic; and (vi) conducting reset operations in the processor in response to the reset signal.

A method of operating an implantable medical device, comprising:
- (i) operating reset logic within the implantable medical device that is independently operable from a processor of the implantable medical device after the implantable medical device is implanted within a patient, wherein the processor is adapted for central control of the implantable medical device;
- (ii) operating a magnetic field sensor in the implantable medical device;
- (iii) generating digital data using, at least, the magnetic field sensor;
- (iv) detecting, by the reset logic, a digital key in the digital data;
- (v) in response to (iv), asserting a reset signal on a pin of the processor by the reset logic;
- and
- (vi) conducting reset operations in the processor in response to the reset signal.
An implantable medical device, comprising:
- a therapy module adapted to provide a therapy to a patient after implantation in the body of the patient;
- a processor adapted for central control of the implantable medical device a magnetic sensor for sensing an external magnetic field;
- and
- reset logic that is independently operable from a processor of the implantable medical device and that is adapted to (i) detect a digital key in digital data generated from a modulated magnetic field detected by the magnetic sensor;
- (ii) in response to detecting the digital key in the digital data, asserting a reset signal on a pin of the processor by the reset logic;
- wherein the processor is adapted to conduct reset operations in response to assertion of the reset signal on the reset pin of the processor.
