- * @file stm32f0xx_crc.c
- * @author MCD Application Team
- * @version V1.3.0
- * @date 16-January-2014
- * @brief This file provides firmware functions to manage the following
- * functionalities of CRC computation unit peripheral:
- * + Configuration of the CRC computation unit
- * + CRC computation of one/many 32-bit data
- * + CRC Independent register (IDR) access
- *

- ##### How to use this driver #####
- ===============================================================================
- [..]
-
- (+) Enable CRC AHB clock using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_CRC, ENABLE)
- function
- (+) If required, select the reverse operation on input data
- using CRC_ReverseInputDataSelect()
- (+) If required, enable the reverse operation on output data
- using CRC_ReverseOutputDataCmd(Enable)
- (+) use CRC_CalcCRC() function to compute the CRC of a 32-bit data
- or use CRC_CalcBlockCRC() function to compute the CRC if a 32-bit
- data buffer
- (@) To compute the CRC of a new data use CRC_ResetDR() to reset
- the CRC computation unit before starting the computation
- otherwise you can get wrong CRC values.
