Abstract
1. 발명이 속하는 기술 분야1. Field of invention
엠-시-유(MCU)를 사용하는 모니터.Monitor using M-Cee-U (MCU).
2. 종래의 문제점에 대한 기술적 과제2. Technical problem of conventional problems
종래의 엠-시-유(MCU)는 전원온시 엠-시-유의 리세트단자에 리세트신호를 보내 엠-시-유를 동작시키게 되는데 이때 외부적인 원인에 의해 수십 m/sec단위로 리세트가 불안전한 경우가 발생할때가 있다. 이런 요인으로 리세트가 불안전할때 이-이-피롬(EEPROM)에 데이타를 라이트할 경우에는 잘못된 데이타가 라이트되거나 또는 데이타가 제대로 쓰여지지 않는 경우가 발생되어 엠-시-유가 오동작하게 되는 문제점이 있었다.The conventional M-C-U (MCU) operates the M-C-U by sending a reset signal to the reset terminal of the M-C-U when the power is turned on. Sometimes the set is unstable. Due to these factors, when the data is written to EEPROM when the reset is unstable, incorrect data may be written or data may not be properly written, causing an incorrect misuse of the M-C. .
3. 발명의 해결하려는 기술적 과제3. Technical problem to be solved of the invention
전원온스타트시에 리세트신호의 불안정으로 발생하는 엠-시-유의 오동작을 시간지연루틴을 통해 방지시킬 수 있도록 하는데 있다.In order to prevent the malfunction of the M-SI-Y caused by the instability of the reset signal at the time of power-on start, the time delay routine can be prevented.
4. 발명의 기술적요지4. Technical summary of invention
전원온시 리세트신호의 불안정으로 발생하는 엠-시-유의 오동작을 방지시켜 주는 시간지연루틴을 구성한 것이 특징이 있다.It is characterized by constructing a time delay routine that prevents the malfunction of the M-SI-U caused by instability of the reset signal at power-on.
