In a communication system of data consisting of first, second microcomputers (1), and (2) for transmitting data according to a state to a driver (3), a key scan is performed to obtain all data and data for executing an operation. The key scan ports 1P1 to 1P6 of the first micom 1 are connected to the key matrix, and the second scan ports 1P1 to 1P6 are connected according to the key scan states of the key scan ports 1P1 to 1P6 of the first microcom 1. The mode data transmission line MDL for transmitting mode data to the microcomputer 2 is connected to the mode data ports MDP1 and MDP2, and the display data according to the operation of the second microcom 2 is transferred to the first microcom. The display data transmission line (DDL) transmitted to (1) is connected to the display data transmission ports (DDP1) and (DDP2). In addition, only the display port DP1 for transmitting display data according to the operation of the first, second microcomputers 1 and 2 is connected to the port DP of the driver 3, and the microcomputer is configured. Serial transmission circuit of data. 제1 마이콤(1)에서 키 스캔한후 상기 스캔된 값이 제1 마이콤(1)의 동작 모드인지 제2마이콤(2)의 동작 모드인지를 판단하는 제1스텝(S1)을 수행하고, 상기 제1스템(S1) 수행결과 스캔된 값이 제1마이콤(1)의 동작 모드이면 제1마이콤(1)의 동작실행 및 디스플레이를 하는 제2스텝(S2)을 수행하며, 상기 스텝(S1) 수행결과 스캔된 값이 제2마이콤(2)의 동작 모드이면 상기 제2마이콤(2)의 동작실행을 하여 상기 디스플레이 데이타 전송라인(DDL)을 통하여 상기 제1마이콤(1)에 디스플레이 데이타를 전송하여 제2마이콤(2)의 동작실행에 따른 데이타를 디스플레이하도록하는 제3스텝(S3)을 수행하도록, 이루어지는 마이콤을 이용한 데이타의 직렬 전송 방법.After key scanning in the first microcomputer 1, a first step S1 of determining whether the scanned value is an operating mode of the first microcomputer 1 or the second microcom 2 is performed. If the scanned value is the operation mode of the first microcomputer 1 as a result of performing the first system S1, a second step S2 of executing and displaying the operation of the first microcomputer 1 is performed. If the scanned value is the operation mode of the second microcom 2, the operation of the second microcom 2 is performed to transmit display data to the first microcom 1 through the display data transmission line DDL. And performing a third step (S3) to display data according to the operation execution of the second microcomputer (2). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
