We want to rely on the internal voltage reference when reading the temperature sensor.

VREFH and VREFL are exposed through external pins – but these are intended for an external, high precision voltage reference.Are these connected continuously or do we have to explicitly connect them using an internal register setting?

You need to connect VREFH and VREFL to external references
