Table 17. Device Status (STATUS) Register Field Descriptions

Bit Field Type Reset Description
7 FL_POR R/W 1h POR flag

Indicates a power-on reset (POR) event has occurred.

0 : Register has been cleared and no POR event has occurred
1 : POR event occurred and has not been cleared. Flag must be cleared by user register write (default).
6 RDY R 0h Device ready flag

Indicates the device has started up and is ready for communication.

0 : ADC ready for communication (default)
1 : ADC not ready
5:1 RESERVED R 00h Reserved

Always write 00h

0 FL_REF R 0h External reference voltage monitor flag

Indicates the selected external reference voltage is lower than 0.3 V. Can be used to indicate a missing external reference voltage.
The reference monitor is enabled with the FL_REF_EN bit in the reference control register (05h).

0 : Differential reference voltage ≥ 0.3 V (default)
1 : Differential reference voltage < 0.3 V
