NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, RPU.
Unless otherwise specified, the parameters given in Table 79 are at ambient temperature
and under the supply voltage conditions summarized in Table 30.
MS32132V4
Maximum frequency is achieved with a duty cycle at (45 - 55%) when loaded by the
specified capacitance.

1. Specified by design, not tested in production.
2. The pull-up is designed with a true resistance in series with a switchable PMOS, whose contribution to the series resistance
is minimal (~10%)
