1. Specified by design, not tested in production.

2. Evaluated by characterization, not tested in production.

3. Measured at VDDA = 3.0 V ±10 mV. The V30 ADC conversion result is stored in the TS_CAL1 byte. Refer to Table 9:

Temperature sensor calibration values.

Continuous mode means Run/Sleep modes, or temperature sensor enable in Low-power run/Low-power sleep modes.
