1. A stimulation therapy method using an implantable medical device (IMD), the IMD including a power supply and a lead system of one or more leads, wherein each lead includes a plurality of electrodes positioned proximate to a tissue of a patient, the method comprising:
obtaining a plurality of program records from an external device, each program record including a plurality of pulse definitions and a plurality of time interval definitions, wherein a pulse definition comprises a set of pulse characteristics to be applied in a particular time interval, wherein each program record of the plurality of program records comprises an indicator indicating whether the program record is a therapy record for applying a stimulation therapy to the patient or a diagnostic record for performing a runtime impedance measurement with respect to the select set of electrodes;
loading a runtime image of a particular program record into an active program buffer; and
interpreting the runtime image to generate control signals to drive an output driver circuit for applying pulse characteristics to a select set of electrodes according to the pulse definitions of the particular program record.
