Abstract

An interface control circuit includes an interface wrapper, a logic circuit, a multiplexer and a command decoder. The interface wrapper transceives a plurality of first signals in a first interface, converts the first signals to a plurality of second signals in a second interface, and generates at least one first command signal according to the first signals. The logic circuit receives the second signals, and generates a second command signal according to the second signals. The multiplexer receives the first command signal and the second command signal, and generates a third command signal according to the first command signal and the second command signal. The command decoder receives the third command signal and generates the decoded command according to the third command signal.
