[bit31 to bit0] D (Data) : Input Data bits
These bits set the input data for the CRC calculation. Software writes the input data for the CRC calculation.
The bit width of 8, 16 or 32 is used. These bits width can be mixed. Bytes or half words can be written into any
position. The address position can be +0, +1, +2 or +3 for byte writing and +0 or +2 for half word writing.
