Description:
8259A是专门为了对8085A和8086/8088进行中断控制而设计的芯片，它是可以用程序控制的中断控制器。单个的8259A能管理8级向量优先级中断。在不增加其他电路的情况下，最多可以级联成64级的向量优先级中断系统。8259A有多种工作方式，能用于各种系统。各种工作方式的设定是在初始化时通过软件进行的。 在总线控制器的控制下,8259A芯片可以处于编程状态和操作状态.编程状态是CPU使用IN或OUT指令对8259A芯片进行初始化编程的状态-
8259A is designed to be on the 8085A and 8086/8088 designed to interrupt control chip, which is the interrupt controller can be programmed. 8259A can manage a single priority interrupt vector 8. Without increasing the other circuit cases, up to 64-level cascaded priority interrupt system vector. 8259A there are several methods of work, can be used in a variety of systems. A variety of work settings is carried out by software initialization. Under the control of the bus controller, 8259A chip can be programmed at the state and operating state. Programming state is CPU use IN or OUT instruction program on the 8259A chip, to initialize the state of
