Abstract
An electronic equipment for communications with other nodes via a serial bus interface. The electronic equipment has a plurality of functions, and stores a plurality piece of information representative of the plurality of functions. The communication system selectively reads the stored information and realizes the function corresponding to the read information. Accordingly, communications suitable for each function can be executed via the serial bus interface. An interface control device used with an electronic equipment having a plurality of functions stores a plurality piece of information representative of the plurality of functions. The communication system selectively reads the stored information and realizes the function corresponding to the read information. Accordingly, the electronic equipment can perform communications suitable for each function.
