Description:
Reading returns the list of possible chip error status.
Available options are:
- 'error_fatal': Analog front-end initialization error
- 'error_i2c': Read/write to non-existing register
- 'error_algorithm': Corrupted parameters
- 'error_calibration': Calibration has failed
- 'error_self_diagnostic': Internal interface failure
- 'error_out_of_range': Measured concentration out of scale
- 'error_memory': Error during memory operations
- 'error_no_measurement': Cleared at first measurement
- 'error_low_voltage': Sensor regulated voltage too low
- 'error_measurement_timeout': Unable to complete measurement

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
