Hi all,
I would like to know the target range of CRC calculation in each SPI communication. Is each CRC calculated from 28-bit payload in that SPI communication as below? Also, is each CRC calculation initialized by 0b1111, not CRC of last communication?
Regards,
RYO
Hi Ryo,
Each CRC calculation is initialized by 0b1111. the CRC is conducted on a 32-bit number, where the first 28 MSB bits are the payload and the last 4 MSB bits are 0’s. The following diagram has more info on this scheme and how to calculate the CRC.
