PURPOSE:To use the titled controller as a monitor between controllers connected serially on an interface by providing both functions to one controller as a master and a slave controller and operating independently both of the said functions. CONSTITUTION:An interface switching logic 11 is a logic controlling transmission/reception of a control signal via an interface and decides whether a control signal A is a signal transmitted to the interface via an exclusive driver or a signal received via an exclusive receiver. A control block switch logic 12 switches the controller so as to be operated as a master or a slave controller and switches control logical blocks 13, 14. This is conducted by using a switching signal 101 or a timing signal from a timing generation circuit 16. Then exclusive memory register groups 15, 17 to control independently the master/ slave control program are provided. |
