A CRC byte can be appended to the output data by configuring CRC_EN to 1b. When the CRC module is enabled, the host must use 32-bit frames for SPI communication. The device outputs the data payload followed by the CRC byte computed over the data payload. Additional 0s can be appended by the ADC after the CRC byte to complete the 32-bit SPI frame (see Table 6-4). The host must compute and compare the CRC corresponding to the data payload with the CRC received from the ADC. The additional 0s appended by the device after the CRC byte must be excluded by the host for computing the CRC.
