摘要

One power management method of a communication interface includes: when receiving a command transmitted via the communication interface, checking if a predetermined criterion is met; and when the predetermined criterion is met, controlling the communication interface to enter a power-saving mode before an end of the received command. Another power management method of a communication interface includes: when the communication interface is operated under a power-saving mode, checking if a predetermined criterion of an executed command is met; and when the predetermined criterion is met, controlling the communication interface to leave the power-saving mode.
