I am trying to use CRC module for CRC-8 calculation. The result I am getting is strange. For example, I put 0x00000002 to INP, 0x00000000 to STAT, and get result equals to 0x32. But it should be 3A.

 

For CRC-8, there are very few description in the reference manual. Does it require any bit reversal or byte swapping? Do I need to use SWAP or INV bits?

 

Thanks.
