Abstract
본발명은 외부펄스를 이용한 리셋감지회로 및 방법에 관한 것으로, 종래에는 마이크로 프로세서가 계속적으로 액티브(ACTIVE)상태에 있어야 타이머로부터 인터럽트 신호를 인식하여 이전 카운트값을 읽을수 있으므로 이러한 경우 소비전력이 많으므로 비효율적이고 터빈이나 회전자가 움직이지 않아 펄스가 발생하지 않아도 타이머에 의해 계속적으로 리드(READ)/라이트(WRITE)작업을 수행해야하는 번거로움과 불필요한 동작으로 인하여 효율이 떨어지는 등의 문제점이 있다. 따라서 본발명은 파워 온시 마이크로프로세서가 액티브 모드로 동작하다가 리셋신호가 입력되면 처음부터 프로그램을 수행하여 동작이 완료되면 계속해서 동작하지 않고 리셋 신호가 올때까지 대기상태로 유지하고 있다가 리셋신호가 입력되면 다시 파워다운 모드를 수행하는 동작을 반복함으로써 소비전력을 1/100정도 줄일수 있도록 한다.The present invention relates to a reset detection circuit and method using an external pulse, conventionally, since the microprocessor must be in an active state continuously to recognize the interrupt signal from the timer and read the previous count value, in this case, the power consumption is high. Inefficient, there is a problem that the efficiency is reduced due to the hassle and unnecessary operation of continuously performing the READ / WRITE operation by the timer even if a pulse does not occur because the turbine or the rotor does not move. Therefore, in the present invention, the microprocessor operates in the active mode at power-on, and when the reset signal is input, the program is executed from the beginning. When the operation is completed, the microprocessor does not continue to operate. When the power supply mode is repeated, the power consumption can be reduced by about 1/100.
