The reset network shown in Figure 37 protects the device against parasitic resets. The user
must ensure that the level on the NRST pin goes below the V_IL max. level specified in
Table 45. Otherwise the reset is not taken into account internally. For power consumption-
sensitive applications, the capacity of the external reset capacitor has to be reduced to limit
the charge/discharge current. If the NRST signal is used to reset the external circuitry, the
user must pay attention to the charge/discharge time of the external capacitor to meet the
reset timing conditions of the external devices. The minimum recommended capacity is 10
nF.
