Abstract
A power supply input selection circuit for selecting one of a plurality of power supply inputs to supply power to a driven circuit. The power supply input selection circuit includes a power supply input switching circuit configured to provide operating power to the driven circuit by routing a selected one of the power supply inputs to the driven circuit as a function of power supply selection information; and a logic circuit configured to change the power supply selection information if a default power mode does not match a desired power mode, the logic circuit being further configured to reset the power supply input selection circuit after changing the power supply selection information, the power supply selection information being maintained during the reset, in which the power supply input switching circuit selects a desired one of the power supply inputs after the logic circuit resets the power supply input selection circuit.
