The reset network shown in Figure 36 protects the device against parasitic resets. The user

must ensure that the level on the NRST pin can go below the VIL max. level specified in

Table 41. Otherwise the reset is not taken into account internally. For power consumption

sensitive applications, the capacity of the external reset capacitor can be reduced to limit

charge/discharge current. If the NRSTsignal is used to reset the external circuitry, care must

be taken of the charge/discharge time of the external capacitor to fulfill the external device’s

reset timing conditions. The minimum recommended capacity is 10 nF.
