The reset network shown in Figure 39 protects the device against parasitic resets. The user

must ensure that the level on the NRST pin can go below VIL(NRST) max (see Table 39:

NRST pin characteristics), otherwise the reset is not taken into account internally.

For power consumption sensitive applications, the external reset capacitor value can be

reduced to limit the charge/discharge current. If NRST signal is used to reset external

circuitry, attention must be taken to the charge/discharge time of the external capacitor to

fulfill the external devices reset timing conditions. Minimum recommended capacity is 10 nF.
