Note: Each of the family devices has unique pattern routes for the internal power and ground. Connect
the power supply voltage to all VDD pins and the ground potential to all GND pins. If a device may
have one or more VDD or GND pins to which the power supply voltage or the ground potential is
not connected, it can not be guaranteed for normal operation.
