1. Specified by design and not tested in production, unless otherwise specified.

2. The input capacitance is negligible compared to the I/O capacitance.

3. Refer to Table 35: Embedded internal voltage reference.

4. No VREFINT division, includes only buffer consumption.

5. VREFINT division, includes resistor bridge and buffer consumption.

6. Evaluated by characterization. Not tested in production.

7. Mostly I/O leakage when used in analog mode. Refer to Ilkg parameter in Table 84: I/O static characteristics.
