In worse power, condition as brown out reset. The reset pin may keep high level but the VDD is low voltage. That
makes the system reset fail and chip error. To connect a diode from reset pin to VDD is a good solution. The circuit can
force the capacitor to release electric charge and drop the voltage, and solve the error.
