23.6.2.4 Sleep Mode Operation
The Voltage Reference output and the Temperature Sensor output behavior during sleep mode can be configured using the Run in Standby bit and the On Demand bit in the Voltage Reference register (VREF.RUNSTDBY, VREF.ONDEMAND), see the following table:
| VREF.ONDEMAND | VREF.RUNSTDBY | Voltage Reference Sleep behavior |
|---|---|---|
| - | - | Disable |
| 0 | 0 | Always run in all sleep modes except Standby Sleep mode |
| 0 | 1 | Always run in all sleep modes including Standby Sleep mode |
| 1 | 0 | Only run if requested by the ADC, in all sleep modes except Standby Sleep mode |
| 1 | 1 | Only run if requested by the ADC, in all sleep modes including Standby Sleep mode |
