mbed_official 76:aeb1df146756 24 using CRC_ReverseOutputDataCmd(Enable)
mbed_official 76:aeb1df146756 25 (+) use CRC_CalcCRC() function to compute the CRC of a 32-bit data
mbed_official 76:aeb1df146756 26 or use CRC_CalcBlockCRC() function to compute the CRC if a 32-bit
mbed_official 76:aeb1df146756 27 data buffer
mbed_official 76:aeb1df146756 28 (@) To compute the CRC of a new data use CRC_ResetDR() to reset
mbed_official 76:aeb1df146756 29 the CRC computation unit before starting the computation
mbed_official 76:aeb1df146756 30 otherwise you can get wrong CRC values.
