NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, RPU (see Table 46).
Unless otherwise specified, the parameters given in Table 49 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 13.
Figure 36.
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 49. Otherwise the reset is not taken into account by the device.

The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution
to the series resistance must be minimum
(~10% order)
