Abstract

본 발명은 1개의 인터럽트 단자를 복수의 목적을 갖는 인터럽트에 병용할 수 있는 장치를 제공한다.The present invention provides an apparatus capable of using one interrupt terminal together with an interrupt having a plurality of purposes.

슬립 모드인 경우에 인터럽트를 걸었을 때에는 마이크로 컴퓨터(5A)가 웨이크 업 모드로의 전환을 판단하고, 또 웨이크 업 모드인 경우에 인터럽트를 걸었을 때에는 마이크로 컴퓨터(5A)가 밧데리 전원이 이탈되었다고 판단하도록, 인터럽트 판별회로(2A)는 상기 인터럽트를 상기 마이크로 컴퓨터(5A)의 1개의 인터럽트 단자(NM1)에 입력한다.In the sleep mode, the microcomputer 5A determines to switch to the wake-up mode when the interrupt is interrupted, and when the interrupt is interrupted in the wake-up mode, the microcomputer 5A determines that the battery power supply is disconnected. The interrupt determination circuit 2A inputs the interrupt to one interrupt terminal NM1 of the microcomputer 5A.

마이크로 컴퓨터의 웨이크 업 장치Microcomputer wake-up device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 일 실시예에 따른 마이크로 컴퓨터 웨이크 업(wake up) 장치를 도시한 블럭도, 제2도는 제1도에서의 블럭 각부의 신호를 도시한 타이밍 챠트도.FIG. 1 is a block diagram showing a microcomputer wake up device according to an embodiment of the present invention, and FIG. 2 is a timing chart showing signals of respective blocks in FIG.

Claims (1)

밧데리 전원에 접속되고, 시스템으로서 동작하지 않는 조건에서는 슬립 모드로 전환되고, 상기 밧데리 전원이 이탈된 경우에 인터럽트를 걸어 메모리 내용을 유지한 후 리셋트되며, 전원을 떨어뜨리고 상기 네트워크 시스템이 동작할 때에는 웨이크 업 모드로 전환되는 마이크로 컴퓨터(5A)와, 상기 슬립 모드인 경우에 인터럽트를 걸었을 때에는, 상기 마이크로 컴퓨터가 웨이크 업 모드로 전환하였다고 판단하고, 또 웨이크 업 모드인 경우에 인터럽트를 걸었을 때에는, 상기 마이크로 컴퓨터가 밧데리 전원이 이탈되었다고 판단하도록 상기 각 인터럽트를 상기 마이크로 컴퓨터의 1개의 인터럽트 단자에 입력하는 인터럽트 판별회로(2A)를 포함하는 것을 특징으로 하는 마이크로 컴퓨터의 웨이크 업 장치.If the battery is connected to the battery power supply and is not operating as a system, the system enters the sleep mode. When the battery power supply is interrupted, an interrupt is interrupted to maintain the memory contents and then reset. When the microcomputer 5A switches to the wake-up mode and interrupts in the sleep mode, it is determined that the microcomputer has switched to the wake-up mode. And an interrupt discrimination circuit (2A) for inputting each interrupt to one interrupt terminal of the microcomputer so that the microcomputer determines that the battery power is removed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
