摘要
Intel82530多规程串行通信控制器是美国英特尔公司推出的继Intel8274芯片后的新品种,其性能和功能等各项指标比8274、8251等同类产品均有明显提高。基于8253O芯片的串行通信应用越来越多,尤其是在采样率较高的实时控制系统中。本文介绍了82530芯片的物理特性,并根据笔者在实际应用中的体会,较详细地介绍了82530芯片的编程要点及芯片在中断处理中的有关问题。
Intel 82530 Multiprotocol Serial Communication controller is the new products folIwing Intel 8274 chip. developed by Intel. Its indexs of function and performances have been greatly improved compared with that of 8274, 8251,etc. 82530 chip - based Serial Communication is being used more and more,especially in real -time control systems of high sampled rate. This paper introduces the physical properties, describes the programming crisis and some problems in interrupt processing of the 82530 chip in detail.
