Abstract
A apparatus, having a processing system and an input buffer coupled with both the processing system and one of two IO pads, and a reference buffer coupled to both the input buffer and the second of the IO pads such that the reference generator controls the input threshold of the input buffer in response to an analog voltage received from an external circuit on the second of the IO pads.
