A method for controlling communication on a bus connecting a first processor, a second processor, and a device. The method transmits a first control signal from the first processor to the second processor via a control signal line, causing a bus connection of the second processor to enter a high-impedance state, transfers data between the device and the first processor via the bus, then setting a bus connection of the first processor to the high-impedance state, and transmits a second control signal from the first processor to the second processor via the control signal line, causing the bus connection of the second processor to exit the high-impedance state.
