Electronic device and associated control method for reducing power consumption

Abstract

An electronic device comprises a clock request pad, a multiplexer and a control circuit. The clock request pad is arranged to refer to a first control signal to operate under a low voltage level or a high voltage level, to indicate whether the electronic device needs a clock signal generated from a clock generation circuit external to the electronic device. Said multiplexer is arranged to refer to a second control signal to output one of a voltage level of the clock request pad and a predetermined voltage level to function as a multiplexer output signal. The control circuit is coupled to said multiplexer, and refers to said multiplexer output signal to determine whether to control the electronic device to operate in a power-saving mode.
