The optional data integrity checks can be configured using the CRC[1:0] bits in the configuration register. When one of the data integrity options is enabled, the data integrity check is output on the TX pin immediately following the conversion or register data; see the Data Integrity section for detailed description of the data integrity functionality. Additional words are always two bytes when CRC16 is enabled. The number of additional words in the inverted data mode when reading conversion data varies from two to three depending on whether the conversion data counter is enabled. Figure 66 and Figure 67 show register and conversion data retrieval when CRC is enabled, respectively. Figure 68 shows data retrieval when inverted data output is enabled.
