Abstract
A method is for choosing a mode out of a set of functioning modes of an integrated circuit (IC) device powered from different supply voltages from respective supply nodes. The IC device may include a mode pin for determining a functioning mode of the device, an internal control circuit coupled to the supply nodes and to the mode pin for sensing an electrical value on the mode pin and to start the IC device in a respective functioning mode depending on the supply node that is powered first. The method may include identifying the different supply voltage that first exceeds a threshold voltage, when the internal control circuit is powered, sensing the electrical value on the mode pin, and powering circuits of the IC device from the different supply voltage that first exceeded the threshold voltage and starting the device in a functioning mode determined by a value of the electrical value sensed on the mode pin and by the different supply voltage that first exceeded the voltage threshold.
