Notes:
1. The above figure is simplified to show an overview of the hardware connection. When designing circuits, make sure to
handle unused pins appropriately to satisfy the electrical characteristics. Connect input-only ports independently to either VDD
or VSS via resistors.
2. Connect pins with names that begin with EVSS to VSS, and pins with names that begin with EVDD to VDD.
3. Make sure to set VDD greater than the detection voltage (VLVI) specified by the LVD.
