* VDD : +4.5 ~ +5.5V
* VPP : VDD + 4V
The ragne of VDD must be from 4.5 to 5.5V and ISP function is not supported under 2MHz system clock.
If the user supplied VDD is out of range, the external power is needed instead of the target system VDD.
For the ISP operation, power consumption required is minimum 30mA.
