Repeat the third step and the fourth step until shift for 8 times, the complete 8 bit is done.

Repeat the second step to the fifth step to treat next 8 bit until all the byte is treated.

The CRC register final value is CRC value.
Besides, there is another CRC calculation method by preset table, its main feature is fast calculating speed, but large saving space is
needed, please refer to related data
