1. A medical device for stimulating a stimulation region of a patient comprising:

  • a waveform generation circuit for generating an output waveform comprised of a plurality of phases each one being configurable in any one of a plurality of different waveform shapes for providing to the stimulation region of the patient;

    a plurality of sets of phase registers, wherein each set of the phase registers includes a respective waveform shape register, and wherein the respective waveform shape register defines the waveform shape for a respective phase of the output waveform; and

    a control device for controlling said waveform generation circuit, wherein said control device comprises a state machine having an interface for receiving at least the plurality of sets of the phase registers as control inputs, said state machine being configured for directing said waveform generation circuit for generating the output waveform in a reproducible and repeatable manner, whereinsaid state machine directs said waveform generation circuit to generate the plurality of phases of the output waveform based on how the waveform shapes for the plurality of phases of the output waveform are defined by the respective waveform shape registers.
