Embedded voltage reference
The parameters given in Table 24 are derived from tests performed under the ambient
temperature and supply voltage conditions summarized in Table 21: General operating
conditions.
1. Continuous mode means Run/Sleep modes, or temperature sensor enable in Low-power run/Low-power sleep modes.
2. Guaranteed by design.
