Timing Channel Circuitry for Creating Pulses in an Implantable Stimulator Device

A method for configuring stimulation circuitry in an implantable stimulator device, the stimulation circuitry for forming pulse phases at electrodes for stimulating a patient's tissue, the method comprising:

• (a) reading data out of the memory for a first pulse phase, the data indicating a number of addresses in which pulse phase parameters are stored in the memory for the first pulse phase and a duration of the first pulse phase;
• (b) if the data indicates more than one address for the first pulse phase, sequentially reading the pulse phase parameters out of the number of addresses in the memory, and providing the pulse phase parameters to the stimulation circuitry to form the first pulse phase at the electrodes for the duration;
• (c) if the first data does not indicate more than one address for the first pulse phase, waiting for the duration;
• (d) after the duration, repeating steps (a)-(d) for a subsequent pulse phase.
