Abstract

본 발명은 텔레비전수상기의 EEPROM에 관한 것으로서, 특히 텔레비전수상기의 작동에 이상이 발생하여 EEPROM을 교환할 때 데이터가 전혀 입력되지 않은 새로운 EEPROM과 데이타가 입력되어 있는 기존의 EEPROM을 자동으로 구별하여 새로운 EEPROM인 경우에 I.D데이타와 초기데이타를 자동으로 입력시키는 텔레비전수상기의 EEPROM교환시 데이타입력방법에 관한 것이다.The present invention relates to an EEPROM of a television receiver. In particular, when an EEPROM is replaced due to an abnormal operation of the television receiver, a new EEPROM is automatically distinguished from a new EEPROM in which no data is input, and an existing EEPROM in which data is input. The present invention relates to a data input method for exchanging EEPROM of a television receiver which automatically inputs ID data and initial data in the case of.

본 발명의 EEPROM교환시 데이타입력방법은 우선 마이크로프로세서의 ㄱ므을 클리어하여, ROM내의 데이타를 이용하여 RAM에 초기데이타를 설정하고, EEPROM의 특정번지의 데이타를 읽어서 마이크로프로세서가 인식하고 있는 I.D 데이타와 읽은 I.D 데이타를 비교하여 동일한 경우에 기존의 EEPROM라고 판단하고 동일하지 않은 경우에 새로운 EEPROM라고 판단하는 방식으로 EEPROM이 신품인지의 여부를 판단하여, 기존의 EEPROM인 경우 EEPROM 데이타를 RAM에 써넣고, EEPROM이 신품인 경우에 EEPROM I.D 데이타를 EEPROM의 특정번지에 써넣은후, 이어서 초기데이타를 EEPROM에 써넣은 단계로 이루어진 것을 특징으로 한다.In the EEPROM exchange of the present invention, the data input method first clears the memory of the microprocessor, sets initial data in the RAM using data in the ROM, reads data at a specific address of the EEPROM, and reads the ID data recognized by the microprocessor. By comparing the read ID data, if it is the same, it is determined that it is an existing EEPROM, and if it is not the same, it is determined whether it is a new EEPROM.In the case of an existing EEPROM, the EEPROM data is written to RAM. When the EEPROM is new, the EEPROM ID data is written to a specific address of the EEPROM, and then the initial data is written to the EEPROM.

Claims

Clearing microprocessor RAM, setting initial data in RAM using data in ROM, reading data at a specific address of EEPROM, comparing ID data recognized by microprocessor with read ID data Determining whether the EEPROM is new by judging that it is an existing EEPROM and if it is not the same, and writing the EEPROM data into RAM when the EEPROM is not a new one and is an existing EEPROM. In the case of a new product, the EEPROM ID data is written to a specific address of the EEPROM, and the initial data is written to the EEPROM.
