Function Documentation

void CRC_DeInit ( void  )

Deinitializes CRC peripheral registers to their default reset values.

Parameters
None
Return values
None
void CRC_ResetDR ( void  )

Resets the CRC calculation unit and sets INIT register content in DR register.

Parameters
None
Return values
None
void CRC_ReverseInputDataSelect ( uint32_t  CRC_ReverseInputData)

Selects the reverse operation to be performed on input data.

Parameters
CRC_ReverseInputData,:Specifies the reverse operation on input data. This parameter can be:
  • CRC_ReverseInputData_No: No reverse operation is performed
  • CRC_ReverseInputData_8bits: reverse operation performed on 8 bits
  • CRC_ReverseInputData_16bits: reverse operation performed on 16 bits
  • CRC_ReverseInputData_32bits: reverse operation performed on 32 bits
Return values
None
void CRC_ReverseOutputDataCmd ( FunctionalState  NewState)

Enables or disable the reverse operation on output data. The reverse operation on output data is performed on 32-bit.

Parameters
NewState,:new state of the reverse operation on output data. This parameter can be: ENABLE or DISABLE.
Return values
None
void CRC_SetInitRegister ( uint32_t  CRC_InitValue)

Initializes the INIT register.

Note
After resetting CRC calculation unit, CRC_InitValue is stored in DR register
Parameters
CRC_InitValue,:Programmable initial CRC value
Return values
None
