AD7124-4 CRC


I have a question regarding AD7124-4 CRC Checksum.

I can easily turn on the CRC check for ROM and RAM but I can not understand CRC for SPI communication.

I turn on CRC SPI by enabling the SPI_CRC_ ERR_EN bit. Thereafter I expect that receive the CRC code after reading the data and status bytes. but I receive no CRC check sum afterwards.

I don't know what is the problem.

May I send the data reading command also with a CRC 8 bit to ADC.

Thank you so much for your time and consideration.
