3.3 Input Data Register (CRCIN)
The Input Data Register (CRCIN) is used to set input data for CRC calculation.

[bit31:0] D[31:0] : Input data bits
These bits are used to set input data for CRC calculation.
Write input data for CRC calculation to this register. There are three types of bit widths: 8-bit, 16-bit, and
32-bit (byte, half word, word), which can be specified together.
The byte and half-word writing positions are arbitrary. The available address positions are as follows.
Byte writing : +0, +1, +2, +3
Half-word writing : +0, +2
