Reset Output
4338F–USB–08/07
As detailed in Section “Hardware Watchdog Timer”, page 155, the WDT generates a 96-
clock period pulse on the RST pin. In order to properly propagate this pulse to the rest of
the application in case of external capacitor or power-supply supervisor circuit, a 1 kΩ
resistor must be added as shown Figure 74.
