NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, R

1. Guaranteed by design, not tested in production.
2. The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution

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 V
