86.7.2 Register programming

• INV or SWAP, or both (affecting the output only) can be applied to CRC-8, CRC-16 and

CRC-32. Both can be applied together.

• SWAP_BITWISE (affecting the input only) can be applied for all polynomials if required by an application.

• SWAP_BYTEWISE (affecting the input only) can be applied for CRC-16 and CRC-32 polynomials only.

• SWAP_BITWISE has priority over SWAP_BYTEWISE when both are applied together.

• When generating CRC-32 for the Ethernet standard the user needs to set

SWAP_BYTEWISE together with INV and SWAP.

• When generating CRC-16 the user needs to set SWAP_BITWISE bit.
