Abstract
An implantable programmable stimulator system includes memory that stores at least one waveform. A playback system provides an output waveform based on retrieving the at least one waveform from the memory. An output system is configured to drive at least one output channel based on the output waveform, the output system selecting the at least one output channel from a plurality of output channels in response to a selection signal.
