Figure 22. Recommended NRST pin protection
1. The external capacitor protects the device against parasitic resets.
2. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in
Table 49: NRST pin characteristics. Otherwise the reset will not be taken into account by the device.

12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 50 are preliminary values derived
from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage
conditions summarized in Table 21: General operating conditions.
Note:
It is recommended to perform a calibration after each power-up.
