Abstract

본 발명은 텔레비전회로의 I²C 버스를 활용하여 제어부(100)가 회로 각 구성부들을 순차적으로 자체점검할 수 있도록 하는 자체고장진단 기능을 구비한 텔레비전에 관한 것이다.The present invention relates to a television equipped with a self-diagnosis function that allows the control unit (100) to sequentially inspect each constituent part of a circuit by utilizing the I²C bus of the television circuit.

본 발명은 텔레비전 회로의 각종 기능부 및 주변장치들에 제어신호를 인가하여 텔레비전의 제반기능제어를 실현하기 위한 마이컴(100)과, 상기 마이컴(100)으로부터 인가되는 제어신호에 따라 각각의 기능들을 수행하도록 구성된 디바이스1(101) 및 디바이스(102)를 포함한 다수개 디바이스들로 이루어지며, 상기 마이컴(100)과 디바이스들(101,102,....)간의 데이타 송수신 I2C 버스방식으로 이루어지는 텔레비전에 있어서, 마이컴 자체고장진단 모드가 데이타버스를 이용하여 디바이스1(101)을 호출하는 단계와, 상기 호출된 디바이스1(101)의 레지스터를 판독해들이는 단계와, 상기 판독레지스터의 최상위 비트가 0 또는 1인지 검사하는 단계와, 상기 검사단계에서 최상위비트가 1이면 전송데이타의 확인신호(ACK)가 수신되는가를 판단하는 단계와, 상기 최상위 비트검사 단계에서 최상위비트가 0이거나 상기 확인(ACK) 수신판단단계에서 확인신호(ACK)가 수신되지 않으면 외부로 디바이스의 고장상태를 표시하는 단계와, 버스에 연결된 나머지 디바이스를 각각에 대하여 순차적으로 상기 기술된 단계들을 적용하는 단계로 이루어지는 것을 특징으로 하는 자체고장진단 기능을 구비한 텔레비전이다.The present invention relates to a microcomputer for realizing control of various functions of a television by applying control signals to various functional units and peripheral devices of a television circuit, (I 2 C) bus system, which is composed of a plurality of devices including a device 1 101 and a device 102 configured to perform data transmission and reception between the microcomputer 100 and the devices 101, 102, (101) by using a data bus; reading out a register of the called device (101); determining whether a most significant bit of the read register 0 " or " 1 ", checking whether an acknowledgment signal (ACK) of transmission data is received if the most significant bit is 1 in the checking step, If the most significant bit is 0 in the checking step or if an acknowledgment signal (ACK) is not received in the acknowledgment (ACK) reception decision step, displaying a failure state of the device externally; And a step of applying the described steps.
