一、概述 1.1 186控打控制器的主要任务。接收打字机来的信息,通过单总线传送给中央处理机,或者从单总线上把中央处理机的信息传给打字机进行打字,即进行数据输入输出的控制。 1.2 本控制器采用单总线标准接口。控制器在执行输入输出操作过程中,一方面要具有操作和控制打字机所必要的逻辑功能,另一方面还要具有把打字机来的信息特征转换成单总线控制的标准格式。
First, an overview 1.1 186 control the main task of the controller. Receives the information from the typewriter, transmits to the central processing unit through the single main line, or transmits the information of the central processing unit from the single main line to the typewriter to carry on the data input / output control. 1.2 The controller uses a single bus standard interface. The controller performs the logic functions required for operation and control of the typewriter on the one hand, and the standard format for conversion of the typewriter’s information features into single-bus control on the other hand.
