这是控制时钟芯片8563读写操作的程序，采用模拟IIC总线的方式,读写函数的入口处先初始化I2C端口为普通IO，出口处再初始化I2C端口为特殊管脚

这个题目是专门正对8563开设的各种程序代码，希望能够帮助各位刚刚入行的同学来进行学习和操作，还有就是如果喜欢的话可以下载-This subject is just for the opening of the 8563 program code, hope to be able to help you just to move into the students to study and operation, and that if you like can download

读取实时时钟的时间，写入时间，实测可以用(ime to read real time clocks, write time)
