8-bit micro-controller  
In power-fail 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. This circuit can force  
the capacitor to release electrical charge and drop the voltage, and solve the error.

LOW VOLTAGE DETECTOR (LVD) DESCRIPTION  
The LVD is a low voltage detector. It detects VDD level and reset the system as the VDD lower than the desired  
voltage. The detect level is 2.4V. If the VDD lower than 2.4V, the system resets. The LVD function is controlled by code  
option. Users can turn on it for special application like power-fail condition. LVD work with external reset function. They  
are OR active.

End of LVD Reset  
The LVD can protect system to work well under Brown-out reset, but it is a high consumptive circuit. In 3V condition,  
the LVD consumes about 100uA. It is a very large consumption for battery system, but supports AC system well.  
Note: LVD is enabled by code option.
