Handling of Unused Pin
Classification
Analog
Digital
Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3)V or less voltage.
TVDD is powered OFF, the power supply current of DVDD at power-down mode may be increased. When
AVDD, HVDD or DVDD is powered OFF, the power supply current of TVDD at power-down mode may be
increased. DVDD and TVDD should not be powered OFF while AVDD or HVDD is powered ON.
(Note 7) Digital
Normal operation is not guaranteed at these extremes.
