Autostatus Readback Mode

If autostatus readback mode is selected, the contents of the

status register is available on the SDO line during every SPI

transaction. When reading back the status register, the SDO

contents differ from the format shown in Table 24. The

contents of the status register is shown in Table 26. The

autostatus readback mode can be used in conjunction with the

ADC sequencer to consecutively monitor up to eight different

ADC inputs. See the ADC Monitoring section for further

details on the ADC sequencer.
