An information handling system includes a planar board and a peripheral interface device. The planar board includes a central processing unit, a baseboard management controller, and an interface logic circuit. The peripheral interface device includes a microcontroller and a serial communication interface device. The peripheral interface device is coupled to a peripheral device. The information handling system also includes an interconnect to couple signals from the planar board to the peripheral interface device. The interconnect includes a single wire to couple first information from the interface logic circuit to the peripheral interface device and to couple second information from the serial communication interface device to the interface logic circuit. The first information includes a first power control command.
