  8.   use CRC  calculation unit to get a CRC code of a given buffer of data word,
  9.   based on a fixed generator polynomial(0x4C11DB7).
  10.   使用循环冗余校验(CRC) 以CRC-32(以太网)多项式(0x4C11DB7)为基础 得到一个32位的CRC计算结果
  11.   CRC技术主要应用于核实数据传输或者数据存储的正确性和完整性。
  12.   ******************************************************************************
  13.   *用途：校验一组数据
  14.   CRC->DR:写操作时，作为输入寄存器，可以输入要进行CRC计算的新数据。
  15.           读操作时，返回上一次CRC计算的结果。
  16.   每一次写入数据寄存器，其计算结果是前一次CRC计算结果和新计算结果的组合(对整个32位字进行CRC计算，而不是逐字节地计算)。
