The connector circuit of TCN and 89C51 is shown in the circuit. All the address input terminals A2~A0 of TCN75 are connected with the high LEV UDD, the address code is set to be 111. 89C51 fulfills the selective function with the software. The 89C51 serial data collecting terminal (RXD) and the serial data emitter(TXD) are linked to SDA and SCL of TCN75. The halt/compare signal of TCN75 is linked to the halt terminal INT0 of 89C51.
