RS485为半双工工作模式,其信号由正负两条线路信号准位相减而得,是差分输入方式,抗共模干扰能力强,即抗噪声干扰性好;实际应用中其传输距离可达1200米。RS485具有多站能力,即一对多的主从通信。在串行通信中,数据通常是在两个站之间传送,按照数据在通信线路上的传送方向可分为3种基本的传送方式:单工、半双工和全双工,如所示。单工、半双工和全双工通信单工通信使用一根导线,信号的传送方和接收方有明确的方向性。

中断程序有条件返回指令CRETI(ConditionalRETurnfromInterrupt)在控制它的逻辑条件满足时从中断程序返回。编程软件自动地为各中断程序添加无条件返回指令。中断连接指令ATCH(AttachInterrupt)用来建立中断事件(EVENT)和处理此事件的中断程序(INT)之间的联系。中断事件由中断事件号指定(见表1),中断程序由中断程序号指定。为某个中断事件指定中断程序后,该中断事件被自动地允许。
