Figure 17. Recommended NRST pin protection
1. The reset network 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 50: NRST pin characteristics. Otherwise the reset will not be taken into account by the device.
3. The external capacitor on NRST must be placed as close as possible to the device.

Analog-to-digital converter characteristics
Unless otherwise specified, the parameters given in Table 52 are preliminary values derived
from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage
conditions summarized in Table 20: General operating conditions.
Note:
It is recommended to perform a calibration after each power-up.
