Abstract
A pin state configuration circuit, a method for configuring pin states and an electronic device for configuring pin states are provided. The pin state configuration circuit includes a configured resistor load, a voltage sampling unit, and a comparator. The voltage sampling unit supplies a reference voltage to the configured resistor load by using a first or second configuration pin, and respectively samples voltages of the first and second configuration pins. The comparator calculates a first voltage ratio based on the voltage of the first configuration pin and the voltage of the second configuration pin, calculates a second voltage ratio based on the voltage of the first configuration pin and the voltage of the second configuration pin, and determines a corresponding pin configuration state based on the first and second voltage ratios. In this way, N×N pin configuration states may be obtained by configuring two configuration pins.
