Abstract
An integrated circuit system includes a first integrated circuit for which signal modes set to a plurality of first I/O ports in the active mode are maintained in the sleep mode and a second integrated circuit for which a plurality of second I/O ports are placed in a floating state in the sleep mode, wherein the first integrated circuit transmits a first notification signal that indicates an operation mode to the second integrated circuit, wherein the second integrated circuit transmits a second notification signal that indicates an operation mode to the first integrated circuit, and wherein the signal modes of the plurality of first I/O ports and the plurality of second I/O ports are set such as to suppress steady currents persistently flowing between the first I/O ports and the second I/O ports, and to suppress through currents flowing.
