R CRC Engine Input Data Count
The number of data items that have been input to the
CRC engine can be read. After the data count reaches
4096, it will wrap around to 0.

The write value should always be 0.
W CRC Engine Input Data
The data to be input to the CRC engine should be
specified here. The specified data is shifted into the
CRC calculation register, starting with the LSB
(CRC_IN0) of the data into the MSB (CRC_REG15)
side of the calculation register. For details, see figure
24.7.
