NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
Unless otherwise specified, the parameters given in Table 36 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 8.

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
. Otherwise the reset will not be taken into account by the device.
