Hello, TI engineers

I want to know CRC of TMS570 only be used in eQEP, ADC, GIO and PINMUX? Could I configure CRC for SPI communication.

Thanks!

Regards!

    Hello Xinyu,

    You can define your own communication protocol for your SPI communication. For example, transmit 2 bytes data first, then 1 byte CRC. The CRC can be calculated by your SW code or the CRC module. If you want to use the CRC module to calculate the CRC, other side (master or slave) of your SPI communication has to use the same CRC formula to calculate and verify the CRC.

    The CRC module can be used to calculate the CRC of any memory region.
