6.3.7.14 ADC Check

This diagnostic mechanism checks ADC functionality and conversion. This check is done by converting a known band-gap voltage, which is completely independent of the ADC reference, and comparing the voltage against the factory-determined tolerance limits.

To run this check, the controller must enable the check and set the scheduling for the run. During this check the AFE is not available for magnetic field conversion. The user can configure the ALERT pin to toggle if an error is detected. This error is also reported in the user register.

Run ModeEvery time a magnetic measurement is initiated and completed
Configuration Register(s)DIAG_EN to enable test. DIAG_SEL to schedule when the test is run
Fault Register Bit TEMP_STAT
Impact if disabledIf disabled, any failures with ADC conversion will not be detected, leading to potentially incorrect errors in the converted magnetic field values.
