串口总线电路的防护设计

Protection design for serial bus circuit

阐述了串口总线电路的防护设计方法,主要对防止串口总线电路吊死的逻辑设计原理进行了较详细的阐述,分析了现有的串口总线电路设计中存在的缺陷,并提出一种通过逻辑控制来实现的串口防护设计方案.该方案实现简单、可靠性高,可广泛应用于各系统的串口总线电路中.

In this paper,we analysed the existing defects of serial bus circuit's design,introduced protection design for serial bus circuit, gave a better way to solve serial bus circuit's protection which realized by logical control.This is easy to realize, highly reliable and widely applied in the serial bus circuit of any systems.
