Each row indicates an aspect of programing the MxN stimulator. For setting stimulation frequency, either 0, 5 or 30 was selected based on the intended frequency of stimulation. The ramp duration setting was identical for stimulation ramp-up as well as stimulation ramp-down. *The MxN accepts 0 Hz as a monophasic DC. $Channel 9 was automatically set to the residual sum of the programable channels (channels 1-8).
