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.
