代码说明：

  PXA255在wince4.2下读写I2C接口实时钟(RTC)以设定系统时间。可以用来学习I2C工作流程或RTC工作原理。替换wince目录下kernalhalarm下的同名文件即可(PXA255 under Wince4.2 I2C interface to read and write real-time clock (RTC) in order to set system time. This code can be used to study the I2C/RTC work flow. Replace the file with same name in the directory of kernal hal arm to work)
