usart串口程序，自发自首电路程序，对ATmage16的usart接口构成的外围硬件电路进行测试-usart

实验目的：熟悉USART通信.串口调试助手发送数据给877，877收到后再转发回串口助手-Experimental Objective: To know USART communications. Serial debugging assistant to send data to 877,877 and then forwarded back to receive the serial Assistant

本程序实现USART异步方式连续接收数据并进行奇校验，在4M的主频下波特率为9600。-USART asynchronous implementation of this procedure to receive data and continuous odd parity, baud rate, under the dominant frequency in the 4M 9600.
