Abstract: Anti-interference design is an important part of the MCU circuit design,mostly the elimination of the interference into the system is considered.This paper proposed the anti-interference detection and response design method.The design of interference detection and response was specially designed to detect and response to the interference of the system,The system was in the waiting state,after the interference disappeared,it entered the normal working state,so as to ensure the reliable work of the system,economically and effectively enhance the anti-interference ability of MCU system,improve the reliability and stability of system operation.

Key words: MCU(Microcontroller Unit), anti-interference, detect and response
