NRST pin characteristics

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

resistor, RPU (see Table 54).

Unless otherwise specified, the parameters given in Table 57 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 24.
