Abstract

본 발명은 VCR의 양방향 동시 시리얼 통신 장치에 관한 것으로, 시리얼 입출력단이 구비되어 있지 않은 시스콘(30)과 마이콘(40)을 사용할 경우 일반 입출력단을 이용하여 상호간 시리얼 통신 가능하도록 하기 위해, 상기 시스템(30)의 클럭에 의해 펄스를 발생시키는 타이머(52)와; 상기 타이머(52)의 펄스에 의해 상기 마이콤(40)에서 선택되어지는 스위칭 IC(54); 및 상기 선택되어진 스위칭 IC(54)를 통해 상기 시스콘(30)과 마이콤(40)의 데이터를 일시 저장하였다가 시프트하도록 되어진 시프트 레지스터(56)로 구성된 인터페이스부를 구비함으로써, 양방향으로 동시에 시리얼 방식에 따라 데이터를 원활하게 송수신할 수 있다는데 그 잇점이 있다.The present invention relates to a bi-directional simultaneous serial communication device of the VCR, in order to enable the serial communication between each other by using a general input and output terminal when using the scone 30 and the microcon 40 is not provided with a serial input and output terminal, A timer 52 for generating a pulse by the clock of the system 30; A switching IC 54 selected by the micom 40 by a pulse of the timer 52; And an interface unit including a shift register 56 configured to temporarily store and shift data of the sheath cone 30 and the microcomputer 40 through the selected switching IC 54, thereby simultaneously operating in a serial manner in both directions. As a result, data can be transmitted and received smoothly.
