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
-
Definition at line 159 of file stm32f30x_crc.c.
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. |
