Function description:
---------------------

This demo shows the calculation of **7 bits CRC**.

Configure the size of the polynomial is 7 bits for CRC7 calculation.

* Configure the CRC7.
* Write data to CRC calculator to start hardware calculation.
* Calculate the result of the CRC7 by software, then to compare with the hardware.

Detail configuration:

Test result:
------------
    
If the output result is same as the result calculated by software according to the theory, then print \"pass\", or print \"fail\".
