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.
