(7) AV pin (Shared with AV
REF
This pin inputs the A/D converter reference voltage.
This pin also functions as an analog power supply pin. Supply power to this pin when the A/D converter is used.
It converts signals input to ANI0 to ANI4 into digital signals according to the voltage applied between AV
AV .

The current flowing in the series resistor string can be reduced by setting the voltage to be input to the AV
pin to AV level in the standby mode.
