AT89C51CC03
As detailed in Section “Watchdog Timer”, page 81, 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 resis-
tor must be added as shown Figure 18.
