The reset network shown in the following figure protects the device against parasitic resets.
The user must ensure that the level on the NRST pin can go below V
#unique_55/CD662
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.
