Abstract

PURPOSE: To prevent a function constituent unit having an answer signal from queuing up forever in case that any slave does not exist or is not output for some reason, by adding a bus supervising method to a function constituent unit to serve as a master.
CONSTITUTION: Bus supervising method 14 is provided so that even when function constituent unit 11 as a master does not receive data transmitted signal 22, the system never breaks down. Bus supervising method 14 is connected to signal line 101 and signal line 102 so as to exercise a supervision over whether data transmitted signal 22 is not received forever. This bus supervising method 14 is provided to all of function constituent units 11W13, but observes and supervise signals on the bus line basically.
