Abstract
A novel method and circuit are disclosed for providing an alternate function to a semiconductor device having a normal operating voltage range and an input pin for receiving an input signal of a voltage level within a normal signal voltage range, for selecting an alternate function, whose steps consist of determining, when a voltage is received at the input pin, whether the voltage is within a normal signal voltage range, enabling the performing of a primary function if the signal voltage is within a normal signal voltage range, and initiating an alternate function when the voltage is outside of the normal signal voltage range.
