Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S

由于采用S3C2440处理器作为主控制器，用到的串口通信比较多，处理器本身的串口不够用，最后决定借用外部芯片来进行扩展满足开发的要求。我传的这代码就是扩展的芯片在Wince系统下 的驱动程序。
