Hi,

We would like to know what is the exact meaning of the VAL field of EVRADCSTAT register. User's Manual says :

This bit indicates if the register is being updated with a new value. Values are updated every EVR cycle.
0B The register is not being updated
1B The register is being updated

When 0, does it mean the ADC measure is not reliable ?

When 1, does it mean the ADC measure is not stable / converging ?

Not clear for us to know when ADCSWDV and ADC13V measure can be safely taken into account.

The User Manual does not say how these measures are done (frequency / trigged by ?). Proably meaningless
Thank you in advance,

Eric Heurtel

Values are updated in a single cycle and therefore consistent within the register irrespective of the VAL bit value. So you can read it anytime.

The Datasheet has the parameter tEVRMON (EVR primary and secondary monitor measurement latency for a new supply value) listed as a maximum of 1.8us.
