CRC0SEL: CRC0 Polynomial Select Bit.
0: CRC0 uses the 32-bit polynomial 0x04C11DB7 for calculating the CRC result. 
1: CRC0 uses the 16-bit polynomial 0x1021 for calculating the CRC result.
CRC0INIT: CRC0 Result Initialization Bit.
Writing a ‘1’ to this bit initializes the entire CRC result based on CRC0VAL.
CRC0VAL: CRC0 Set Value Select Bit
This bit selects the set value of the CRC result.
0: CRC result is set to 0x00000000 on write of ‘1’ to CRC0INIT.
1: CRC result is set to 0xFFFFFFFF on write of ‘1’ to CRC0INIT.
These bits specify which byte of the CRC result will be read/written on the next access to
CRC0DAT. The value of these bits will auto-increment upon each read or write.
For CRC0SEL = 0:
00: CRC0DAT accesses bits 7–0 of the 32-bit CRC result.
01: CRC0DAT accesses bits 15–8 of the 32-bit CRC result.
10: CRC0DAT accesses bits 23–16 of the 32-bit CRC result.
11: CRC0DAT accesses bits 31–24 of the 32-bit CRC result.
For CRC0SEL = 1:
00: CRC0DAT accesses bits 7–0 of the 16-bit CRC result.
01: CRC0DAT accesses bits 15–8 of the 16-bit CRC result.
10: CRC0DAT accesses bits 7–0 of the 16-bit CRC result.
11: CRC0DAT accesses bits 15–8 of the 16-bit CRC result.
Each write to CRCIN results in the written data being computed into the existing CRC result.
