    TLE5012B. CRC calculation trouble.

    Hello! I am using TLE5012B via SSC interface (bit bang mode, not hardware spi, connection according to the datasheet). I write to sensor command 0x8012 (read angle value) and then i get two words (angle value + safety word). For example: command word: 0x8012, response words: 0xCDAC and 0x1F0B.
    My calculated CRC is 0xED. But the CRC part in safety word is 0x0B. I must note that angle value is CORRECT during the 360 degrees of magnet rotating. Tell me please what's the problem? P.S. In attachment you can see the example of transaction. Click image for larger version

    Please try one of the C-code samples provided in section "5.2.4 Cyclic Redundancy Check (CRC)" of the user's manual?

    Thanks for request! I am using CRC calculaton from datasheet. I am also using two variants of CRC calculation (with table and without) so i get the similar results.

    A need to note that somewhere in datasheet CRC calculation takes safety word too and somewhere to calculate CRC only need coomand word and response word (without safety word). Maybe i dont understand the algorithm..
