&par Example Description

Write the calculated data to CRC DATA register and get the calculated result.
The phenomenon of ComputedCRC compases ExpectedCRC. The results will 
be displayed on serial assistant through USART1.

&par Hardware Description

using USART1(TX:PA9、RX:PA10).
  - USART1 configured as follow:
  - BaudRate = 115200 
  - Word Length = USART_WordLength_8b
  - Stop Bit = USART_StopBits_1
  - Parity = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
