4.2 Temperature Sensor and Voltage Reference Start-Up

Prior to measuring either VTEMP or VBG, the Temperature Sensor and Voltage Reference module must be enabled:
  1. Set the ADC_TEMPMR.TEMPON bit.
  2. Wait for the specified start-up time.

Considering its low-power consumption(1), in most cases there is no benefit to disabling this module between two temperature measurements.

Note:
  1. About 200 µA max. Refer to the SAMA7D6 Series data sheet for more details.
