摘要:
An IC chip allows first communication for performing communication with all of the other IC chips, and second communication for performing communication while restricting communication parties. That is to say, the IC chip performs sending/receiving signals with a new communication arrangement with both the first communication which is a broadcasting arrangement and the second communication which is a communicatory arrangement. This enables the function upgrading electronic equipment to be performed easily, and enables flexible signal processing with a new communication arrangement.
