Reset Controlled by an
External Superviser Device
As the reset pin can be forced in output by the Watch-Dog timer (WDT) or the POR/PFD
features, there can be a conflict between the external superviser device and the micro-
controller’s reset pin when in one side the external superviser is pulling the reset pin to
VCC and in another side the WDT or POR/PFD features tries to force the reset pin to
ground. Therefore, it recommended to insert a series resistor of 1.8K +/-10% or a diode
(1N4148 for instance) between the external superviser device and the reset pin as
detailed in the following figures.
