ABSTRACT:
A circuit in an integrated circuit having an input terminal to be coupled to a resistor network for selecting one of multiple digital states in the integrated circuit includes a voltage decode circuit, a control circuit and a power-up control circuit. The first input terminal receives an input voltage having a voltage value associated with the multiple digital states. The voltage decode circuit receives the input voltage and generates a voltage decode signal indicative of the voltage value of the input voltage. The control circuit receives the voltage decode signal and generates an output control signal accordingly where the output control signal selects one of the multiple digital states. The power-up control circuit provides power to the resistor network, the voltage decode circuit and the control circuit for determining the selected digital state and disconnects power to those circuits after the selected digital state is determined.
