Description: 数字I/O实验主要完成的功能：
在此实验中，SEED-DEC5416 首选进行初始化，包括对外设 UART、本身频率的设定及一些状态区的初始化。然后等待 SEED-MMI5402 发送命令；SEED－DEC5416 响应交通灯自动模式、交通灯手动手动模式、交通灯东西通、交通灯南北通、及交通灯的禁行与夜间模式的操作命令。同时还响应，对 SEED-DEC5416 的复位及两个单元之间的通讯故障。

Description: 利用51的两个输入输出引脚如P1.0和P1.1，置1或0分别代表高低电
平，也就是串口通信中所说的位，如起始位用低电平，则将其置0，停止位为高电平，则将其置
1，各种数据位和校验位则根据情况置1或置0。-Using 51 as the two input and output pins P1.0 and P1.1, set to 1 or 0 representing the high and low, that is said in the bit serial communication, such as the use of low starting position, will be its set to 0, stop bit is high, then it is set to 1, all data bits and the parity bit set to 1 according to the situation or set to 0.
