Cautions 1. Be sure to apply V
DD before applying VPP, and remove it after removing VPP.
2. VPP must not exceed +13.5 V including overshoot voltage.
3. Disconnecting/inserting the device from/to the on-board socket while +12.5 V is being applied
to the V
PP pin may have an adverse affect on device reliability.
