Figure 24. Recommended NRST pin protection
1. The reset network protects the device against parasitic resets.
2. The external capacitor must be placed as close as possible to the device.
3. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in
Table 60. Otherwise the reset will not be taken into account by the device.

12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 61 are derived from tests
performed under ambient temperature, fPCLK frequency and VDDA supply voltage conditions
summarized in Table 23: General operating conditions.
Note:
It is recommended to perform a calibration after each power-up.
